Description

Technical Field

[0001] The present invention relates to the technical field of sweeping robots, and in particular to a sweeping robot. Background Art

[0002] As an efficient cleaning tool designed for modern lazy people, sweeping robots have been widely recognized and used in modern families due to their automation and intelligence. Such devices usually integrate multiple functions such as sweeping, vacuuming and even mopping, greatly reducing the user's housework burden. However, despite the continuous advancement of technology, existing sweeping robots still face some pain points that users have concentrated on reporting.

[0003] The primary problem is that the hair on the ground, especially in the gaps between carpets and floors, is not cleaned well. Long hair or pet hair can easily get tangled in the cleaning parts of the sweeping robot, such as the bristles of the sweeping roller, which not only affects the cleaning efficiency, but may also cause the sweeping roller to rotate poorly or even be damaged. In addition, once the hair is entangled in the brush of the sweeping roller, users often need to clean it manually, which not only increases the complexity of use, but may also cause the brush to wear faster due to frequent cleaning, thereby shortening the service life of the sweeping robot and increasing the user's purchase cost.

[0004] To address this problem, there are some products on the market that try to reduce hair entanglement by improving the material or design of the sweeping roller, but the results are not ideal. For example, although using hard bristles can reduce entanglement to a certain extent, it sacrifices the ability to clean soft surfaces (such as carpets); and increasing the gap between bristles can reduce entanglement, but it may cause fine dust and hair to be missed, affecting the cleaning effect. Summary of the invention

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

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

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

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

[0011] In a specific embodiment, the main body is further provided with a transverse baffle between the rolling brush member and the accommodating cavity.

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

[0015] In a specific embodiment, the cleaning component is composed of a motor and a cleaning blade, the motor is fixed to the main body, and the cleaning blade is transmission-connected to the output shaft of the motor.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0037] See also Figures 1 to 8 In the specific embodiment shown, the present invention discloses a sweeping robot, comprising: a main body 10, a cleaning component 20, a centrifugal fan blade 30, a driving member 40 and a dust box 50, the main body 10 is provided with a accommodating cavity 11 and an installation cavity 12 which are connected to each other, the accommodating cavity 11 is used to install the driving member 40 and the centrifugal fan blade 30, and the centrifugal fan blade 30 is transmission-connected to the driving member 40, the dust box 50 is installed in the installation cavity 12, the cleaning component 20 is installed on the main body 10 and is located at the front side of the centrifugal fan blade 30, the cleaning component 20 works to push debris to the area where the centrifugal fan blade 30 is located, and the driving member 40 drives the centrifugal fan blade 30 to rotate to absorb the debris and blow it into the dust box 50.

[0038] Specifically, by integrating multiple functional modules such as the cleaning component 20, the centrifugal fan blades 30, the driving component 40 and the dust box 50, a complete cleaning system is formed. The cleaning component 20 is responsible for pushing the debris on the ground (such as dust, debris, hair, etc.) to the area where the centrifugal fan blades 30 are located, and the driving component 40 drives the centrifugal fan blades 30 to rotate at high speed, generating a strong suction force, quickly sucking the debris and blowing it into the dust box 50, thereby improving the cleaning efficiency and effect. In addition, by connecting the accommodating cavity 11 and the mounting cavity 12 to each other, and rationally arranging the positions of the cleaning component 20, the centrifugal fan blades 30 and the dust box 50, the airflow path is optimized, so that the debris can be smoothly sucked into the dust box 50, reducing the airflow resistance, thereby reducing energy consumption and improving the endurance of the sweeping robot. In addition, the sweeping robot adopts a modular design. Key components such as the cleaning component 20, centrifugal fan blades 30, drive components 40 and dust box 50 can be installed and disassembled independently. This design is not only convenient for users to perform daily maintenance and cleaning, but also enables the sweeping robot to easily upgrade various functional modules in the future to adapt to changing cleaning needs. In addition, since the sweeping robot can automatically complete the entire process of cleaning, sucking up debris and collecting it into the dust box 50, users no longer need to perform tedious manual cleaning work, which greatly improves the user experience. In addition, the efficient cleaning efficiency and optimized energy consumption performance also make the sweeping robot an indispensable cleaning tool for modern families.

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

[0040] Specifically, by arranging the blade 60 inside the centrifugal fan blade 30, the power generated by the rotation of the fan blade is cleverly utilized, so that the blade 60 can rotate synchronously and cut the debris passing through it. This design is particularly aimed at hair, pet hair and other slender and easily entangled debris, effectively avoiding them from affecting the normal operation of the sweeping robot due to entanglement. The debris after cutting is smaller in volume and easier to be sucked into the dust box 50, thereby significantly improving the debris handling ability of the sweeping robot. In addition, when facing slender debris, the traditional sweeping robot often requires the user to manually clean the debris entangled on the cleaning parts, which is not only time-consuming and laborious, but also may cause damage to the cleaning parts. The sweeping robot effectively reduces the occurrence of debris entanglement through the cutting action of the blade 60, thereby reducing the user's maintenance cost and complexity. In addition, the setting of the blade 60 not only solves the problem of debris entanglement, but also further optimizes the airflow path of the sweeping robot. The cut debris is more easily driven by the airflow and smoothly enters the dust box 50 along the optimized path, thereby improving the dust collection efficiency. In addition, due to the cutting action of the blade 60, the sweeping robot can more effectively handle various debris on the ground, especially those long and thin debris that are difficult for traditional sweeping robots to handle. This not only improves the cleaning effect, but also allows users to enjoy a smoother and more efficient cleaning experience during use.

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

[0042] Specifically, the three blades 60 are evenly distributed radially on the inner side of the centrifugal fan blade 30, ensuring that the centrifugal fan blade 30 can be evenly cut in any direction during the rotation process. This design avoids the problem of poor cutting effect or entanglement of debris caused by uneven distribution of the blades 60, thereby improving the overall cleaning efficiency of the sweeping robot. In addition, the setting of the three blades 60 increases the cutting area, allowing the sweeping robot to cut off slender debris such as hair, pet hair, etc. more quickly; at the same time, since the number of blades 60 is moderate and evenly distributed, the load between them is also relatively balanced, which helps to extend the service life of the blades 60 and reduce wear and replacement frequency. In addition, the even distribution of the three blades 60 also helps to optimize the airflow distribution of the sweeping robot. During the rotation of the centrifugal fan blade 30, the airflow can pass through the gap between the blades 60 more smoothly, reducing airflow resistance and energy loss, which not only improves the dust collection efficiency of the sweeping robot, but also reduces energy consumption and extends battery life. In addition, since the blade elements 60 are evenly distributed, the sweeping robot can more effectively handle various debris on the ground, no matter in which direction they are located. This design enhances the cleaning range and adaptability of the sweeping robot, enabling it to cope with various complex cleaning environments.

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

[0044] Specifically, the introduction of the roller brush 70 enables the sweeping robot to have a more comprehensive cleaning capability. The roller brush 70 can effectively remove stubborn stains, fine dust and highly adhesive debris on the ground, such as chewing gum residues, pet footprints, etc., by rotating and cleaning. This auxiliary cleaning method significantly improves the cleaning effect of the sweeping robot and provides users with a cleaner living environment. In addition, the rotating cleaning action of the roller brush 70 and the suction function of the centrifugal fan blades 30 complement each other to form a more efficient cleaning system. After the centrifugal fan blades 30 suck the debris into the dust box 50 through the airflow, the roller brush 70 rotates to clean the remaining debris. This collaborative operation method greatly shortens the cleaning time and improves the cleaning efficiency of the sweeping robot. In addition, the design of the roller brush 70 enables the sweeping robot to cover areas that are difficult to reach with traditional vacuuming methods, such as deep in the carpet fibers and gaps in furniture. These areas often hide a lot of dust and debris that are difficult to detect. The meticulous cleaning of the roller brush 70 effectively solves this problem and expands the cleaning range of the sweeping robot. In addition, the auxiliary cleaning function of the roller brush 70 not only improves the cleaning effect, but also allows users to enjoy a more convenient and efficient cleaning experience during use. Users no longer need to worry about stubborn stains and fine dust on the ground. The sweeping robot can easily handle it, greatly reducing the user's housework burden. In addition, 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 the frequency of use and cleaning needs to ensure that it always maintains the best working condition. This design not only extends the service life of the roller brush 70, but also reduces the overall maintenance cost of the sweeping robot.

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

[0046] Specifically, the setting of the transverse baffle 80 is like a barrier, which effectively prevents hair, pet hair and other slender debris on the ground from being drawn into the roller brush member 70 on the rear side. This design fundamentally solves the problem of hair entangled in the roller brush member 70, and avoids the problems of poor rotation of the roller brush member 70, reduced cleaning efficiency and even component damage caused by hair entanglement. In addition, due to the blocking effect of the transverse baffle 80, the roller brush member 70 can focus more on cleaning dust, debris and other debris on the ground without being disturbed by hair and other slender debris, which not only improves the cleaning efficiency of the roller brush member 70, but also enables the sweeping robot to clean the ground more thoroughly, bringing a cleaner living environment to the user. In addition, the entanglement of hair and other slender debris is one of the main reasons for the damage of the roller brush member 70. By adding the transverse baffle 80, the contact opportunity between the roller brush member 70 and these debris is effectively reduced, thereby extending the service life of the roller brush member 70 and reducing the maintenance cost of the user.

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

[0048] Specifically, the introduction of the roller member 90 enables the sweeping robot to move freely on various ground surfaces, including smooth tiles, wooden floors, and carpets. The design of the roller member 90 generally takes into account good contact with the ground and the reduction of rolling friction, thereby ensuring the flexibility and stability of the sweeping robot during movement. This design enables the sweeping robot to easily shuttle between furniture, cover every corner of the room, and achieve comprehensive cleaning. In addition, the roller member 90 generally has a certain elasticity or shock-absorbing design to adapt to different ground materials and height changes. This design enables the sweeping robot to easily cross obstacles such as thresholds and carpet edges when encountering obstacles, avoiding jamming or stagnation caused by uneven ground or obstacles. In addition, by accurately controlling the rotation direction and speed of the roller member 90, the sweeping robot can plan the optimal cleaning path to avoid repeated cleaning and missing areas. This intelligent path planning capability not only improves cleaning efficiency, but also saves the user's valuable time; at the same time, the stable movement of the roller member 90 also provides the sweeping robot with continuous and stable cleaning power, ensuring uniform and consistent cleaning effects. In addition, the design of the roller member 90 usually takes into account the needs of noise reduction and energy saving. By adopting low-noise materials, optimizing the roller structure, and accurately controlling the rotation speed, the sweeping robot can reduce noise and energy consumption during operation while ensuring the cleaning effect. This not only provides users with a more comfortable home environment, but also meets the modern family's pursuit of environmental protection and energy saving. In addition, the introduction of the roller member 90 enables the sweeping robot to have more outstanding mobility and adaptability, thereby bringing users a more convenient and efficient cleaning experience. Users no longer need to worry about the movement of the sweeping robot and can focus more on other housework or leisure activities; at the same time, the stable movement and intelligent path planning of the roller member 90 also improve the user's trust and satisfaction with the cleaning effect of the sweeping robot.

[0049] More specifically, the specific number and installation positions of the roller members 90 can be set according to actual needs, which will not be elaborated in detail here.

[0050] See also Figures 1 to 7 As shown, in one embodiment, the number of the cleaning components 20 and the number of the accommodating chambers 11 are both two, and they are distributed on both sides of the main body 10.

[0051] Specifically, the number of cleaning components 20 and accommodating chamber 11 is two, so as to form a design of double cleaning components 20 and double centrifugal fan blades 30. The double cleaning components 20 can work simultaneously, covering a wider cleaning area, significantly shortening the time required for cleaning; at the same time, the design of double centrifugal fan blades 30 enhances the dust suction ability, so that the sweeping robot can more effectively absorb and collect dust, debris, hair and other debris on the ground, thereby achieving a significant improvement in cleaning efficiency. In addition, the double cleaning components 20 can adopt different cleaning methods (such as rotating brushes, side brushes, etc.), which can clean the ground more comprehensively, especially the edges and corners that are difficult to reach. The double centrifugal fan blades 30 enhance the airflow and improve the capture ability of fine particles, further optimizing the cleaning effect. In addition, distributing the two cleaning components 20 and the two centrifugal fan blades 30 on both sides of the main body 10 helps to balance the weight distribution of the sweeping robot, making it more stable during movement. This design reduces the tilting or jamming caused by excessive weight on one side, and improves the continuity and stability of cleaning. In addition, the design of the dual cleaning components 20 and the dual centrifugal fan blades 30 enables the sweeping robot to distribute the workload more evenly and reduces excessive wear of a single component. This design helps to extend the overall service life of the sweeping robot and reduce the user's maintenance costs.

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

[0053] Specifically, the circular main body 10 design enables the sweeping robot to use space more efficiently for movement and cleaning, especially in hard-to-reach areas such as furniture and corners. The fan-shaped dust box 50 makes full use of the limited space inside the main body 10, improves the dust collection capacity, and maintains the overall compactness and smoothness of the sweeping robot. In addition, the design that the end face of the dust box 50 is flush with the end face of the main body 10 makes the sweeping robot more neat and beautiful in appearance. This integrated design not only improves the overall texture of the product, but also reduces the user's perception of the protruding part of the dust box 50 when using it, and enhances the comfort and convenience of use. In addition, the design that the dust box 50 is flush with the end face of the main body 10 makes it more convenient and quick for users to replace or clean the dust box 50; at the same time, this design also reduces the gap between the dust box 50 and the main body 10, reducing the risk of dust and debris entering the interior of the sweeping robot, thereby simplifying maintenance and cleaning work. In addition, the circular body 10 design makes the sweeping robot more stable during movement, reducing the tilting or jamming caused by the irregular shape, and the fan-shaped dust box 50 fits tightly with the body 10, further enhancing the overall stability of the sweeping robot. In addition, this design also helps to reduce the noise and vibration of the sweeping robot during operation, improving the safety and comfort of use.

[0054] See also Figure 1 to Figure 2 As shown, in one embodiment, the cleaning assembly 20 is composed of a motor and cleaning blades, the motor is fixed to the main body 10, and the cleaning blades are drivingly connected to the output shaft of the motor.

[0055] Specifically, the motor, as a power source, can stably and efficiently drive the cleaning blades to rotate, thereby generating sufficient cleaning force, effectively removing dust, debris, hair and other debris on the ground and pushing them to the area where the centrifugal fan blades 30 are located. This design ensures that the sweeping robot can maintain a continuous and stable cleaning effect during the cleaning process, thereby improving the cleaning efficiency. In addition, the motor is directly fixed to the main body 10, and the cleaning blades are connected to the output shaft of the motor in a transmission manner. This design makes the structure of the cleaning component 20 more compact and reduces unnecessary space occupation; at the same time, this highly integrated design also reduces the overall complexity of the sweeping robot and improves the reliability and durability of the product. In addition, since the connection method between the motor and the cleaning blades is simple and clear, the user can operate more conveniently when the cleaning component 20 needs to be maintained or replaced. This design not only reduces the maintenance cost, but also improves the user's experience. In addition, the design of the motor-driven cleaning blades enables the sweeping robot to adjust the speed and power of the motor according to different cleaning needs, thereby achieving effective cleaning of different material floors and different types of debris. This flexibility and adaptability enable the sweeping robot to be more widely used in various home and commercial environments.

[0056] In one embodiment, the driving member 40 is a DC motor.

[0057] Specifically, the output shaft of the DC motor drives the centrifugal fan blades 30 to rotate to absorb debris. With its high speed and high power, the DC motor can efficiently drive the centrifugal fan blades 30 to rotate quickly and generate strong suction. This design enables the sweeping robot to easily absorb dust, debris, hair and other debris on the ground, and even tiny particles deeply embedded in the carpet fibers, significantly improving the cleaning efficiency and quality. Compared with other types of motors, the noise generated by the DC motor during operation is relatively low, thanks to its advanced electromagnetic design and optimized mechanical structure, which enables the motor to maintain a low noise level when running at high speed. This low noise characteristic provides users with a more comfortable cleaning environment and reduces interference and discomfort during use. In addition, the DC motor has a higher energy efficiency ratio, that is, it can more effectively convert electrical energy into mechanical energy, which means that under the same cleaning task, the DC motor consumes less electrical energy, thereby achieving the goal of energy saving and environmental protection. In addition, the DC motor has excellent speed regulation performance, and the speed can be adjusted according to actual needs to further reduce energy consumption.

[0058] See also Figures 2 to 3 As shown, in one embodiment, the main body 10 is further provided with a control module 100, and the cleaning assembly 20, the driving member 40, the roller brush member 70 and the roller member 90 are all electrically connected to the control module 100, and the control module 100 is used to control the operation of the cleaning assembly 20, the driving member 40, the roller brush member 70 and the roller member 90. The control module 100 and the control method of the control module 100 both adopt the existing public technology, and no further explanation is given here.

[0059] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
