[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0038] In one embodiment of the present invention, a sweeping robot is provided, including a vacuuming system, a walking system, and a power supply system. The vacuuming system is used to collect dust on the ground, the walking system is used to drive the sweeping robot to move, and the power supply system is used to provide energy for the vacuuming system and the walking system to work.

[0039] The vacuuming system includes a roller brush mechanism, a dust collection box, an air duct, and a fan. The dust collection box is connected to the outlet of the roller brush mechanism, and the air duct connects the dust collection box and the fan. When the roller brush mechanism is working, it picks up dust from the ground, and then the suction generated by the fan draws the dust-mixed air into the robot vacuum cleaner. When the dust-mixed airflow passes through the dust collection box, the dust is filtered into the dust collection box, and the clean air is discharged from the air duct after passing through the fan, thus realizing the vacuuming function.

[0040] See Figure 1 The roller brush mechanism 200 includes a housing, a roller brush assembly 210, and a roller brush cover assembly 100. The roller brush cover assembly 100 is fitted with the housing and encloses it to form a roller brush cavity. The roller brush assembly 210 is disposed within the roller brush cavity for mounting and protecting the roller brush assembly 210. Specifically, the housing has an opening through which the roller brush assembly 210 is disposed, and the roller brush cover assembly 100 is placed over the opening and fitted with the housing. Thus, a roller brush cavity is formed between the housing and the roller brush cover assembly 100 for mounting the roller brush assembly 210 within the roller brush cavity.

[0041] See Figures 2-5In some embodiments, the roller brush cover assembly 100 includes a pressure plate 10, a roller brush cover 30, and a scraper 50. The pressure plate 10 includes a plate body 12, and the roller brush cover 30 includes a cover body 32. A buckle 14 is provided on one of the plate body 12 and the cover body 32, and a latching position 34 is provided on the other. The buckle 14 and the latching position 34 engage with each other to allow the plate body 12 and the cover body 32 to mate. Simultaneously, the scraper 50 abuts against the roller brush cover 30 and the pressure plate 10. Thus, the pressure plate 10 is mounted on the roller brush cover 30 through the engagement of the buckle 14 and the latching position 34, thereby fixing the scraper 50 between the scraper 50 and the roller brush cover 30. When the robot vacuum cleaner is working, the scraper 50 gathers debris from the floor to the suction port, facilitating the cleaning of the debris by the roller brush assembly 210. Moreover, during the assembly of the roller brush cover assembly 100, only the buckle 14 and the snap-fit ​​34 need to be engaged, and no fasteners are required, which simplifies the assembly process and improves work efficiency.

[0042] The roller brush cover 30 has a suction port that communicates with the roller brush chamber. The roller brush assembly 210 can contact the ground through the suction port to pick up dust and other debris on the ground. Then, the debris is sucked into the sweeping robot by negative pressure to complete the vacuuming work.

[0043] See Figures 4-7 Furthermore, in the longitudinal direction parallel to the extension direction of the scraper 50, the plate 12 has two opposing first sides 121; in the second direction perpendicular to the first direction, the plate 12 has two opposing second sides 123; there are multiple buckles 14, with buckles 14 provided on both the first sides 121 and the second sides 123 of the plate 12, and multiple fastening positions 34 provided on the cover 32 corresponding to the buckles 14, with each buckle 14 engaging with the corresponding fastening position 34. In effect, multiple sets of buckles 14 and fastening positions 34 are provided, spaced apart along the circumference of the plate 12, and buckles 14 are provided on both the first sides 121 and the second sides 123 in the circumference. This allows multiple buckles 14 to form multiple engagement points between the plate 12 and the cover 32, improving the assembly reliability of the plate 12 and the cover 32.

[0044] Furthermore, both first sides 121 of the plate 12 are provided with latches 14, which is equivalent to... Figure 2 In the view shown, buckles 14 are provided on both the left and right sides of the pressure plate 10 to improve the fastening effect between the pressure plate 10 and the roller brush cover 30.

[0045] In some embodiments, a limiting member is provided on one of the plate 12 and the cover 32, and a limiting groove is provided on the other of the plate 12 and the cover 32; the limiting member is fitted into the limiting groove in a direction perpendicular to the direction of the pressure plate 10 pointing towards the roller brush cover 30. In this way, the relative position of the plate 12 and the cover 32 is positioned by the cooperation of the limiting member and the limiting groove, so that the pressure plate 10 is fitted into the preset position of the roller brush cover 30 to compress and fix the scraper 50.

[0046] Furthermore, the limiting component includes a first limiting component 15 disposed on the plate 12, and the limiting groove includes a first limiting groove 35 disposed on the cover 32; the first limiting component 15 is positioned within the first limiting groove 35 in a direction perpendicular to the direction of the pressure plate 10 pointing towards the roller brush cover 30. Thus, by providing the first limiting component 15 on the plate 12 and the first limiting groove 35 on the cover 32, during assembly, the first limiting component 15 on the plate 12 is aligned with the first limiting groove 35, and then the plate 12 is pressed towards the cover 32, so that the buckle 14 engages with the latch 34, thereby completing the conversion of the roller brush cover assembly 100.

[0047] Furthermore, a buckle 14 is provided on one of the two second sides 123 of the plate 12, and a first limiting member 15 is provided on the other of the two second sides 123. In this way, buckles 14 and first limiting members 15 are provided on both sides of the plate 12 respectively, so as to position and fasten from different directions and improve assembly efficiency.

[0048] In some embodiments, the limiting member includes a second limiting member 17 disposed on the plate 12, and the limiting groove includes a second limiting groove 37 disposed on the cover 32; the second limiting member 17 is positioned within the second limiting groove 37 in a direction perpendicular to the direction from the pressure plate 10 to the roller brush cover 30; and the second limiting member 17 is located between the two first sides 121 and between the two second sides 123, with the second limiting groove 37 corresponding to the second limiting member 17. This is equivalent to setting the second limiting member 17 in the central region of the plate 12, and through the coordinated positioning of the first limiting member 15 located on the outer periphery and the second limiting member 17 located in the center, the pressure plate 10 is accurately positioned onto the roller brush cover 30.

[0049] In some embodiments, the limiting member includes a third limiting member 39 disposed on the cover 32, and the limiting groove includes a third limiting groove 19 disposed on the plate 12; the third limiting member 39 is fitted into the third limiting groove 19 in a direction perpendicular to the direction of the pressure plate 10 pointing towards the roller brush cover 30. Thus, by providing a first limiting member 15, a second limiting member 17, and a third limiting groove 19 on the plate 12, and a first limiting groove 35, a second limiting groove 37, and a third limiting member 39 on the cover 32, the limiting members are provided on both the plate 12 and the cover 32, and the two mutually limit each other, further improving the positioning accuracy and ensuring installation reliability.

[0050] Furthermore, in the direction from one side 123 to the other of the two second sides 123 of the plate 12, the second limiting member 17 is located between the first limiting member 15 and the third limiting groove 19; in the direction from one side 121 to the other of the two first sides 121 of the plate 12, multiple first limiting members 15, second limiting members 17, and third limiting grooves 19 are provided at intervals, and multiple first limiting grooves 35, second limiting grooves 37, and third limiting members 39 are correspondingly provided at intervals. That is, a row of first limiting members 15, a row of second limiting members 17, and a row of third limiting grooves 19 are provided on the plate 12, and a positioning structure is provided in the area covering the entire surface of the plate 12, which greatly improves the positioning accuracy and assembly reliability.

[0051] Understandably, the first limiting member 15, the second limiting member 17, and the third limiting member 39 can be set to different shapes. For example, the first limiting member 15 can be set to a cube, and the second limiting member 17 and the third limiting member 39 can be set to cylinders, so as to facilitate identification and alignment of different limiting groups and facilitate assembly.

[0052] Based on the same concept, in one embodiment of the present invention, a roller brush mechanism 200 as described above is also provided. The roller brush mechanism 200 includes a housing, a roller brush assembly 210, and a roller brush cover assembly 100. The roller brush cover assembly 100 is fitted with the housing and encloses it to form a roller brush cavity. The roller brush assembly 210 is disposed within the roller brush cavity for mounting and protecting the roller brush assembly 210. Specifically, the housing has an opening, through which the roller brush assembly 210 is disposed within the housing. The roller brush cover assembly 100 covers the opening and is fitted with the housing. Thus, a roller brush cavity is formed between the housing and the roller brush cover assembly 100 for mounting the roller brush assembly 210 within the roller brush cavity.

[0053] In some embodiments, the roller brush cover assembly 100 includes a pressure plate 10, a roller brush cover 30, and a scraper 50. The pressure plate 10 includes a plate body 12, and the roller brush cover 30 includes a cover body 32. A buckle 14 is provided on one of the plate body 12 and the cover body 32, and a latching position 34 is provided on the other. The buckle 14 and the latching position 34 engage with each other to allow the plate body 12 and the cover body 32 to mate. Simultaneously, the scraper 50 abuts against the roller brush cover 30 and the pressure plate 10. Thus, the pressure plate 10 is mounted on the roller brush cover 30 through the engagement of the buckle 14 and the latching position 34, thereby fixing the scraper 50 between the scraper 50 and the roller brush cover 30. When the robot vacuum cleaner is working, the scraper 50 gathers debris from the floor to the suction port, facilitating the cleaning of the debris by the roller brush assembly 210. Moreover, during the assembly of the roller brush cover assembly 100, only the buckle 14 and the snap-fit ​​34 need to be engaged, and no fasteners are required, which simplifies the assembly process and improves work efficiency.

[0054] Based on the same concept, in one embodiment of the present invention, a roller brush cover 30 as described above is also provided. The roller brush cover assembly 100 includes a pressure plate 10, a roller brush cover 30, and a scraper 50. The pressure plate 10 includes a plate body 12, and the roller brush cover 30 includes a cover body 32. A buckle 14 is provided on one of the plate body 12 and the cover body 32, and a latching position 34 is provided on the other. The buckle 14 and the latching position 34 engage with each other to allow the plate body 12 and the cover body 32 to mate. Simultaneously, the scraper 50 abuts against the roller brush cover 30 and the pressure plate 10. Thus, the pressure plate 10 is mounted on the roller brush cover 30 through the engagement of the buckle 14 and the latching position 34, thereby fixing the scraper 50 between the scraper 50 and the roller brush cover 30. When the sweeping robot is working, the scraper 50 gathers debris on the ground into the suction port, facilitating the cleaning of the debris by the roller brush assembly 210. Moreover, during the assembly of the roller brush cover assembly 100, only the buckle 14 and the snap-fit ​​34 need to be engaged, and no fasteners are required, which simplifies the assembly process and improves work efficiency.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
