Description

Technical Field

[0001] This invention relates to the field of robotic vacuum cleaners, and more particularly to a robotic vacuum cleaner. Background Technology

[0002] Robotic vacuum cleaners, as efficient cleaning tools designed specifically for modern, less busy people, have gained widespread acceptance and application in modern homes thanks to their automation and intelligence. These devices typically integrate multiple functions such as sweeping, vacuuming, and even mopping, greatly reducing the burden of housework for users. However, despite continuous technological advancements, existing robotic vacuum cleaners still face some pain points that users have frequently reported.

[0003] The primary problem lies in its ineffectiveness in cleaning hair from floors, especially carpets and floor crevices. Long hair or pet fur easily gets tangled in the cleaning components of the robot vacuum, such as the bristles of the sweeping roller. This not only affects cleaning efficiency but can also cause the sweeping roller to malfunction or even be damaged. Furthermore, once hair gets tangled in the sweeping roller brushes, users often need to clean it manually. This not only increases the complexity of use but can also lead to accelerated brush wear due to frequent cleaning, thus shortening the robot vacuum's lifespan and increasing the user's purchase cost.

[0004] To address this issue, some products on the market have attempted to reduce hair entanglement by improving the material or design of the sweeping roller, but the results have not been ideal. For example, while using stiff bristles can reduce entanglement to some extent, it sacrifices the ability to clean soft surfaces (such as carpets); and while increasing the gaps between the bristles can reduce entanglement, it may cause fine dust and hair to be missed, affecting the cleaning effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a sweeping robot.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention provides a robotic vacuum cleaner, comprising: a main body, a cleaning component, a centrifugal fan, a drive unit, and a dust collection box. The main body has a receiving cavity and an installation cavity that are interconnected. The receiving cavity is used to install the drive unit and the centrifugal fan, and the centrifugal fan is throttle-connected to the drive unit. The dust collection box is installed in the installation cavity. The cleaning component is installed on the main body and located in front of the centrifugal fan. The cleaning component operates to push debris to the area where the centrifugal fan is located. The drive unit drives the centrifugal fan to rotate, suck up the debris, and blow it into the dust collection box.

[0008] In one specific embodiment, the inner side of the centrifugal fan blade is further provided with a blade, which is used to cut the debris.

[0009] In one specific embodiment, the number of blades is three, and they are radially and evenly distributed on the inner side of the centrifugal fan blade.

[0010] In one specific embodiment, the main body located in the area of ​​the dust collection box is further provided with a roller brush, and the dust collection box is provided with a cleaning port corresponding to the roller brush.

[0011] In one specific embodiment, the main body is further provided with a transverse baffle between the roller brush and the receiving cavity.

[0012] In one specific embodiment, the main body is further provided with a plurality of roller components.

[0013] In one specific embodiment, there are two cleaning components and two receiving cavities, which are distributed on both sides of the main body.

[0014] In one specific embodiment, the main body is circular and the dust collection box is fan-shaped. When the dust collection box is fixed in the mounting cavity, the end face of the dust collection box is flush with the end face of the main body.

[0015] In one specific embodiment, the cleaning assembly consists of a motor and cleaning blades, the motor being fixed to the main body, and the cleaning blades being drivenly connected to the output shaft of the motor.

[0016] In one specific embodiment, the driving component is a DC motor.

[0017] The sweeping robot of the present invention has the following advantages compared with the prior art: by integrating multiple functional modules such as sweeping components, centrifugal fan blades, drive components and dust collection boxes, a complete sweeping system is formed. The sweeping components are responsible for pushing debris (such as dust, debris, hair, etc.) on the ground to the area where the centrifugal fan blades are located, while the drive components drive the centrifugal fan blades to rotate at high speed, generating a strong suction force to quickly suck up the debris and blow it into the dust collection box, thereby improving the sweeping efficiency and effect.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0037] See Figures 1 to 8 The present invention discloses a sweeping robot, comprising: a main body 10, a sweeping component 20, a centrifugal fan 30, a drive component 40, and a dust collection box 50. The main body 10 is provided with a receiving cavity 11 and a mounting cavity 12 that are interconnected. The receiving cavity 11 is used to install the drive component 40 and the centrifugal fan 30, and the centrifugal fan 30 is tractively connected to the drive component 40. The dust collection box 50 is installed in the mounting cavity 12. The sweeping component 20 is installed on the main body 10 and located in front of the centrifugal fan 30. The sweeping component 20 works to push debris to the area where the centrifugal fan 30 is located. The drive component 40 drives the centrifugal fan 30 to rotate, suck up the debris, and blow it into the dust collection box 50.

[0038] Specifically, by integrating multiple functional modules such as the cleaning component 20, centrifugal fan 30, drive unit 40, and dust collection box 50, a complete cleaning system is formed. The cleaning component 20 is responsible for pushing debris (such as dust, crumbs, and hair) on the ground to the area where the centrifugal fan 30 is located, while the drive unit 40 drives the centrifugal fan 30 to rotate at high speed, generating strong suction to quickly suck up the debris and blow it into the dust collection box 50, thereby improving cleaning efficiency and effectiveness. In addition, by connecting the receiving cavity 11 and the mounting cavity 12 and rationally arranging the positions of the cleaning component 20, centrifugal fan 30, and dust collection box 50, the airflow path is optimized, allowing debris to be smoothly sucked into the dust collection box 50, reducing airflow resistance, thereby reducing energy consumption and improving the robot vacuum's endurance. Furthermore, this robotic vacuum cleaner adopts a modular design, with key components such as the cleaning assembly 20, centrifugal fan 30, drive unit 40, and dustbin 50 all capable of independent installation and disassembly. This design not only facilitates daily maintenance and cleaning for users but also allows for easy upgrades to various functional modules in the future to adapt to ever-changing cleaning needs. Additionally, because the robotic vacuum cleaner can automatically complete the entire process of sweeping, sucking up debris, and collecting it in the dustbin 50, users no longer need to perform tedious manual cleaning, thus greatly enhancing the user experience. Moreover, its high cleaning efficiency and optimized energy consumption make it an indispensable cleaning tool for modern families.

[0039] See Figure 2 , Figure 3 and Figure 8 As shown, in one embodiment, the inner side of the centrifugal fan 30 is further provided with a blade 60, which is used to cut the debris.

[0040] Specifically, by ingeniously utilizing the power generated by the rotation of the centrifugal fan blades 30, the blades 60 rotate synchronously and cut away debris flowing nearby. This design is particularly effective against long, thin, and easily tangled debris such as hair and pet fur, preventing them from interfering with the robot's normal operation. The cut debris is smaller and easier to suck into the dust collection box 50, significantly improving the robot's debris handling capabilities. Furthermore, traditional robot vacuums often require users to manually remove debris tangled in the cleaning components when dealing with long, thin objects. This is not only time-consuming and laborious but can also damage the cleaning components. The blades 60 effectively reduce debris entanglement, lowering maintenance costs and complexity for users. In addition, the blades 60 not only solve the debris entanglement problem but also optimize the airflow path of the robot. The cut debris is more easily carried by the airflow and smoothly enters the dust collection box 50 along the optimized path, thus improving dust collection efficiency. In addition, due to the cutting action of the blade 60, the robot vacuum cleaner can handle various debris on the ground more effectively, especially those long and thin debris that are difficult for traditional robot vacuum cleaners to handle. This not only improves the cleaning effect, but also allows users to enjoy a smoother and more efficient cleaning experience.

[0041] See Figure 2 , Figure 3 and Figure 8 As shown, in one embodiment, the number of blades 60 is three, and they are radially and evenly distributed on the inner side of the centrifugal fan blade 30.

[0042] Specifically, three blades 60 are radially and evenly distributed on the inner side of the centrifugal fan 30, ensuring that the airflow in any direction is evenly cut during the rotation of the centrifugal fan 30. This design avoids the problems of poor cutting effect or debris entanglement caused by uneven distribution of the blades 60, thereby improving the overall cleaning efficiency of the robot vacuum cleaner. In addition, the arrangement of three blades 60 increases the cutting area, allowing the robot vacuum cleaner to cut long and thin debris, such as hair and pet hair, more quickly. At the same time, because the number of blades 60 is moderate and their distribution is even, the load among them is also relatively balanced, which helps to extend the service life of the blades 60 and reduce wear and replacement frequency. Furthermore, the even distribution of the three blades 60 also helps to optimize the airflow distribution of the robot vacuum cleaner. During the rotation of the centrifugal fan 30, the airflow can pass more smoothly through the gaps between the blades 60, reducing airflow resistance and energy loss. This not only improves the dust collection efficiency of the robot vacuum cleaner but also reduces energy consumption and extends battery life. In addition, because the blades are evenly distributed, the robot vacuum cleaner can handle various debris on the ground more effectively, regardless of their orientation. This design enhances the cleaning range and adaptability of the robot vacuum cleaner, enabling it to cope with various complex cleaning environments.

[0043] See Figures 2 to 5 As shown, in one embodiment, the main body 10 is further provided with a roller brush 70 in the area of ​​the dust collection box 50, and the dust collection box 50 is provided with a cleaning port 51 corresponding to the roller brush 70.

[0044] Specifically, the introduction of the roller brush 70 gives the robot vacuum cleaner a more comprehensive cleaning capability. Through its rotating cleaning action, the roller brush 70 effectively removes stubborn stains, fine dust, and highly adhesive debris such as chewing gum residue and pet paw prints from the floor. This auxiliary cleaning method significantly improves the cleaning effect of the robot vacuum cleaner, providing users with a cleaner living environment. Furthermore, the rotating cleaning action of the roller brush 70 complements the suction function of the centrifugal fan 30, forming a more efficient cleaning system. After the centrifugal fan 30 sucks debris into the dust collection box 50 through airflow, the rotating roller brush 70 cleans up any remaining debris. This collaborative operation greatly shortens cleaning time and improves the cleaning efficiency of the robot vacuum cleaner. Furthermore, the design of the roller brush 70 allows the robot vacuum to reach areas that traditional vacuuming methods struggle to access, such as deep within carpet fibers and furniture crevices. These areas often harbor large amounts of hard-to-detect dust and debris, and the roller brush 70's meticulous cleaning effectively solves this problem, expanding the robot vacuum's cleaning range. In addition, the roller brush 70's auxiliary cleaning function not only improves cleaning performance but also provides users with a more convenient and efficient cleaning experience. Users no longer need to worry about stubborn stains and fine dust on the floor; the robot vacuum can easily handle them, significantly reducing the burden of housework. Moreover, as an independent component, the roller brush 70 is easy to disassemble and clean. Users can regularly maintain and service the roller brush 70 according to usage frequency and cleaning needs, ensuring it remains in optimal working condition. This design not only extends the lifespan of the roller brush 70 but also reduces the overall maintenance cost of the robot vacuum.

[0045] See Figures 1 to 7 As shown, in one embodiment, the main body 10 is further provided with a transverse baffle 80 between the roller brush 70 and the receiving cavity 11.

[0046] Specifically, the horizontal baffle 80 acts like a barrier, effectively preventing long, thin debris such as hair and pet hair from being drawn into the rear roller brush 70. This design fundamentally solves the problem of hair entanglement in the roller brush 70, avoiding issues such as sluggish rotation, reduced cleaning efficiency, or even component damage caused by hair entanglement. Furthermore, due to the blocking effect of the horizontal baffle 80, the roller brush 70 can focus more intently on cleaning dust, debris, and other imperfections on the floor without being interfered with by long, thin debris like hair. This not only improves the cleaning efficiency of the roller brush 70 but also allows the robot vacuum to clean the floor more thoroughly, providing users with a cleaner living environment. Additionally, entanglement of long, thin debris like hair is one of the main causes of damage to the roller brush 70. By adding the horizontal baffle 80, the contact between the roller brush 70 and these debris is effectively reduced, thereby extending the lifespan of the roller brush 70 and lowering user maintenance costs.

[0047] In one embodiment, the main body 10 is further provided with a plurality of roller components 90.

[0048] Specifically, the introduction of the roller component 90 allows the robot vacuum to move freely on various surfaces, including smooth tiles, wooden floors, and carpets. The design of the roller component 90 typically considers good contact with the ground and reduced rolling friction, ensuring the robot vacuum's flexibility and stability during movement. This design allows the robot vacuum to easily navigate between furniture, covering every corner of the room for thorough cleaning. Furthermore, the roller component 90 usually has a certain degree of elasticity or shock absorption to adapt to different floor materials and height variations. This design allows the robot vacuum to easily overcome obstacles such as thresholds and carpet edges, avoiding jamming or stalling caused by uneven surfaces or obstacles. In addition, by precisely controlling the rotation direction and speed of the roller component 90, the robot vacuum can plan the optimal cleaning path, avoiding repeated cleaning and missed areas. This intelligent path planning capability not only improves cleaning efficiency but also saves users valuable time. Simultaneously, the stable movement of the roller component 90 provides the robot vacuum with continuous and stable cleaning power, ensuring even and consistent cleaning results. Furthermore, the design of the roller component 90 typically takes noise reduction and energy conservation into account. By using low-noise materials, optimizing the roller structure, and precisely controlling the rotation speed, the robot vacuum can reduce noise and energy consumption during operation while ensuring cleaning effectiveness. This not only provides users with a more comfortable home environment but also aligns with modern families' pursuit of environmental protection and energy conservation. In addition, the introduction of the roller component 90 gives the robot vacuum superior mobility and adaptability, resulting in a more convenient and efficient cleaning experience. Users no longer need to worry about the robot vacuum's movement and can focus more on other household chores or leisure activities. Simultaneously, the stable movement and intelligent path planning of the roller component 90 also increase user trust and satisfaction with the robot vacuum's cleaning performance.

[0049] More specifically, the exact number and installation position of the roller components 90 can be set according to actual needs, and will not be elaborated on here.

[0050] See Figures 1 to 7 As shown, in one embodiment, there are two cleaning components 20 and two receiving cavities 11, which are distributed on both sides of the main body 10.

[0051] Specifically, there are two cleaning components 20 and two receiving cavities 11, forming a design with dual cleaning components 20 and dual centrifugal fan blades 30. The dual cleaning components 20 can work simultaneously, covering a wider cleaning area and significantly shortening the cleaning time. Simultaneously, the dual centrifugal fan blades 30 enhance suction power, enabling the robot vacuum to more effectively adsorb and collect dust, debris, hair, and other impurities from the floor, thus greatly improving cleaning efficiency. Furthermore, the dual cleaning components 20 can employ different cleaning methods (such as rotating brushes and side brushes) to more thoroughly clean the floor, especially hard-to-reach edges and corners. The dual centrifugal fan blades 30, by enhancing airflow, improve the capture of fine particles, further optimizing the cleaning effect. Additionally, distributing the two cleaning components 20 and the two centrifugal fan blades 30 on both sides of the main body 10 helps balance the weight distribution of the robot vacuum, making it more stable during movement. This design reduces tilting or jamming caused by excessive weight on one side, improving the continuity and stability of cleaning. In addition, the design of the dual cleaning components 20 and dual centrifugal fan blades 30 allows the robot vacuum cleaner to distribute the workload more evenly and reduce excessive wear on individual parts. This design helps to extend the overall service life of the robot vacuum cleaner and reduce the user's maintenance costs.

[0052] See Figures 1 to 2 As shown, in one embodiment, the main body 10 is circular and the dust collection box 50 is fan-shaped. When the dust collection box 50 is fixed in the mounting cavity 12, the end face of the dust collection box 50 is flush with the end face of the main body 10.

[0053] Specifically, the circular main body 10 design allows the robot vacuum cleaner to move and clean more efficiently, especially in hard-to-reach areas such as furniture and corners. The fan-shaped dustbin 50 makes full use of the limited internal space of the main body 10, increasing dust collection capacity while maintaining the overall compactness and sleekness of the robot vacuum cleaner. Furthermore, the flush design of the dustbin 50 with the end face of the main body 10 makes the robot vacuum cleaner look cleaner and more aesthetically pleasing. This integrated design not only enhances the overall quality of the product but also reduces the user's perception of the protruding dustbin 50, enhancing comfort and convenience. Additionally, the flush design of the dustbin 50 with the end face of the main body 10 makes it easier and faster for users to replace or clean the dustbin 50. At the same time, this design reduces the gap between the dustbin 50 and the main body 10, lowering the risk of dust and debris entering the robot vacuum cleaner's interior, thus simplifying maintenance and cleaning. In addition, the circular body 10 design makes the robot vacuum cleaner more stable during movement, reducing tilting or jamming caused by irregular shape. The fan-shaped dust collection box 50 fits tightly with the body 10, further enhancing the overall stability of the robot vacuum cleaner. Furthermore, this design also helps reduce noise and vibration during operation, improving safety and comfort during use.

[0054] See Figures 1 to 2 As shown, in one embodiment, the cleaning assembly 20 consists of a motor and cleaning blades, the motor is fixed to the main body 10, and the cleaning blades are driven to the output shaft of the motor.

[0055] Specifically, the motor, as the power source, can stably and efficiently drive the sweeping blades to rotate, thereby generating sufficient sweeping force to effectively remove dust, debris, hair, and other impurities from the ground and push them to the area where the centrifugal fan 30 is located. This design ensures that the robot vacuum cleaner maintains a continuous and stable cleaning effect during the cleaning process, improving cleaning efficiency. Furthermore, the motor is directly fixed to the main body 10, and the sweeping blades are driven by the motor's output shaft. This design makes the structure of the sweeping component 20 more compact, reducing unnecessary space occupation. At the same time, this highly integrated design also reduces the overall complexity of the robot vacuum cleaner, improving the product's reliability and durability. In addition, because the connection between the motor and the sweeping blades is simple and clear, users can more easily operate when they need to maintain or replace the sweeping component 20. This design not only reduces maintenance costs but also improves the user experience. Moreover, the motor-driven sweeping blade design allows the robot vacuum cleaner to adjust the motor speed and power according to different cleaning needs, thereby achieving effective cleaning of different floor materials and different types of debris. This flexibility and adaptability allows the robot vacuum cleaner to be more widely used in various home and commercial environments.

[0056] In one embodiment, the drive element 40 is a DC motor.

[0057] Specifically, the output shaft of the DC motor drives the centrifugal fan 30 to rotate, thereby sucking up debris. With its high speed and high power, the DC motor efficiently drives the centrifugal fan 30 to rotate rapidly, generating powerful suction. This design allows the robot vacuum to easily pick up dust, debris, hair, and other impurities from the floor, even tiny particles deeply embedded in carpet fibers, significantly improving cleaning efficiency and quality. Compared to other types of motors, DC motors produce relatively low noise during operation. This is thanks to their advanced electromagnetic design and optimized mechanical structure, which allows the motor to maintain a low noise level even at high speeds. This low-noise characteristic provides users with a more comfortable cleaning environment, reducing interference and discomfort during use. Furthermore, DC motors have a higher energy efficiency ratio, meaning they can more effectively convert electrical energy into mechanical energy. This means that under the same cleaning task, DC motors consume less electrical energy, thus achieving the goal of energy conservation and environmental protection. In addition, DC motors have excellent speed control performance, allowing the speed to be adjusted according to actual needs, further reducing energy consumption.

[0058] See Figures 2 to 3 As shown, in one embodiment, the main body 10 is further provided with a control module 100. The cleaning component 20, the drive component 40, the roller brush component 70, and the roller component 90 are all electrically connected to the control module 100. The control module 100 is used to control the operation of the cleaning component 20, the drive component 40, the roller brush component 70, and the roller component 90. The control module 100 and its control method both adopt existing publicly available technologies, which will not be elaborated on here.

[0059] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
