Description

Technical Field

[0001] The present invention relates to the technical field of intelligent appliances, and particularly to a roller brush cover, a roller brush mechanism and a floor cleaning robot. Background Art

[0002] With the development of economy and the progress of society, people's requirements for the quality of life are getting higher and higher. Therefore, some intelligent appliances that can liberate human hands have emerged as the times require. Among them, as a kind of intelligent household appliances, the floor cleaning robot plays an increasingly important role in people's daily life.

[0003] Generally, a floor cleaning robot includes a dust suction system, a traveling system and a power supply system. The dust suction system is used to collect dust on the ground, the traveling system is used to drive the floor cleaning robot to move, and the power supply system is used to provide working energy for the dust suction system and the traveling system. Generally, the dust suction system includes a roller brush mechanism, and the roller brush mechanism includes a housing, a roller brush assembly and a roller brush cover. The roller brush assembly is arranged in the housing, the roller brush cover is covered on the housing, and a dust suction port allowing the roller brush assembly to contact the ground is formed on the roller brush cover. When the roller brush assembly rotates, dust is driven up through the dust suction port for adsorption cleaning. However, when the traditional roller brush mechanism performs cleaning work towards the ground, if there is relatively high garbage on the ground, the garbage will lift the roller brush mechanism, resulting in a large gap between the roller brush mechanism and the ground and affecting the dust suction and cleaning effect. Summary of the Invention

[0004] Aiming at the problem of poor dust suction and cleaning effect of traditional floor cleaning robots, the present invention provides a roller brush cover, a roller brush mechanism and a floor cleaning robot, which can achieve the technical effect of improving the cleaning performance.

[0005] A roller brush cover, the roller brush cover includes a cover body, and a dust suction port and an avoidance groove are formed on the cover body, and the dust suction port is used to allow the exposed roller brush assembly;

[0006] Wherein, the cover body has a first direction parallel to the axial direction of the roller brush assembly, a second direction perpendicular to the axial direction of the roller brush assembly, and a third direction perpendicular to both the first direction and the second direction; along the second direction, the cover body has an outer side and an inner side; the avoidance groove is formed on the outer side of the cover body, and the avoidance groove is formed along the third direction.

[0007] The above-mentioned roller brush cover includes a cover body, which is used to be assembled on the housing, and a dust suction port is provided on the cover body. The dust suction port is used to expose the roller brush assembly, so that when the roller brush assembly rotates, it can contact the ground through the dust suction port to perform cleaning work. Moreover, along the second direction, the cover body has opposite inner and outer sides. When the cover body is assembled on the housing, the outer side of the cover body faces the ground, and the inner side of the cover body faces the inside of the floor sweeping robot. The roller brush assembly sucks the garbage on the external ground into the inside of the floor sweeping robot on the inner side of the cover body through the dust suction port.

[0008] Moreover, an avoidance groove is provided on the outer side of the cover body. The avoidance groove is opened along a third direction perpendicular to the first direction and the second direction, which is equivalent to the avoidance groove being opened along the traveling direction of the floor sweeping robot. In this way, when the floor sweeping robot works, the outer side of the cover body faces the ground, and the floor sweeping robot travels along the third direction perpendicular to the axial direction of the roller brush assembly. The extending direction of the avoidance groove is the same as the traveling direction of the floor sweeping robot. During the traveling process of the floor sweeping robot, it can be misaligned with the garbage on the ground through the avoidance groove, preventing the roller brush cover from being lifted after contacting the garbage on the ground, preventing a large gap from being generated between the roller brush cover and the ground, ensuring that the floor sweeping robot can reliably adhere to the ground for dust suction and cleaning during the traveling process, and improving the dust suction and cleaning effect of the floor sweeping robot.

[0009] In one embodiment, the avoidance groove has an inlet and an outlet that communicate with each other in the third direction.

[0010] In one embodiment, along the first direction parallel to the axial direction of the roller brush assembly, the outer side of the cover body has a third outer surface and a fourth outer surface located on opposite sides of the dust suction port;

[0011] The avoidance groove is provided on the third outer surface and / or the fourth outer surface.

[0012] In one embodiment, along the first direction, the avoidance groove has opposite first side walls and second side walls;

[0013] Wherein, the first side wall is located between the second side wall and the dust suction port; relative to the bottom wall of the avoidance groove, the second side wall is lower than the first side wall.

[0014] In one embodiment, along the third direction, both the third outer surface and the fourth outer surface have a lower side and a higher side;

[0015] Relative to the dust suction port, the lower side is lower than the higher side.

[0016] In one embodiment, the bottom wall of the avoidance groove includes a first bottom wall, a second bottom wall, and a third bottom wall. The first bottom wall is on the same side as the lower side, the second bottom wall is on the same side as the higher side, and the third bottom wall is obliquely connected between the first bottom wall and the second bottom wall.

[0017] In one embodiment, along the third direction, the outer side of the cover body has a first outer surface and a second outer surface located on opposite sides of the dust suction port. Both the first outer surface and the second outer surface are connected between the third outer surface and the fourth outer surface. The first outer surface is on the same side as the lower side, and the second outer surface is on the same side as the higher side;

[0018] Relative to the dust suction port, the first outer surface is lower than the second outer surface.

[0019] In one embodiment, the cover body includes a main body, a first guiding rib, and a second guiding rib. The dust suction port is formed on the main body. Both the first guiding rib and the second guiding rib extend along the third direction, and the first guiding rib and the second guiding rib are arranged at intervals. An avoidance groove is formed between the first guiding rib and the second guiding rib.

[0020] In one embodiment, the first guiding rib is located between the second guiding rib and the dust suction port;

[0021] Relative to the main body, the second guiding rib is lower than the first guiding rib.

[0022] In one embodiment, the roller brush cover further includes a guiding portion; along the first direction, the dust suction port has opposite first and second ends, and at least one of the first end and the second end is provided with a guiding portion extending into the dust suction port;

[0023] Wherein, in the direction in which the first end or the second end connected to the guiding portion points to the dust suction port, the guiding portion is inclined towards the inner side of the cover body.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0035] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0036] In the present invention, unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0038] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate 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 intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0039] Referring to Figures 1-2 , in an embodiment of the present invention, a floor sweeping robot 200 is provided, which includes a dust collection system, a traveling system and a power supply system. The dust collection system is used to collect dust on the ground, the traveling system is used to drive the floor sweeping robot 200 to move, and the power supply system is used to provide working energy for the dust collection system and the traveling system.

[0040] The dust collection 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 134 of the roller brush mechanism, and the air duct is connected between the dust collection box and the fan. When the roller brush mechanism works, it picks up the dust on the ground, and then through the suction force generated by the fan, the air mixed with dust is sucked into the interior of the floor sweeping robot 200. When the air flow mixed with dust passes through the dust collection box, the dust is filtered in the dust collection box, and the clean air is discharged after passing through the fan through the air duct, thus realizing the dust collection function.

[0041] Referring to Figures 3-6 , the roller brush mechanism includes a housing, a roller brush assembly 210 and a roller brush cover 100. The housing has an opening, the roller brush assembly 210 is disposed in the housing through the opening, and the roller brush cover 100 is covered at the opening and is mated with the housing. In this way, an accommodating space is formed between the housing and the roller brush cover 100, and the roller brush assembly 210 is assembled in the accommodating space. Specifically, the roller brush assembly 210 includes a roller brush, a rubber brush and a brush disposed on the roller brush, etc. When the roller brush assembly 210 rotates, it contacts the ground to drive up the dust on the ground.

[0042] When the floor sweeping robot 200 is placed on the ground for work, the roller brush cover 100 is covered on the housing and faces the ground. The roller brush cover 100 may directly contact the ground or the garbage on the ground, which will affect the working performance of the floor sweeping robot 200. Therefore, the design of the roller brush cover 100 is relatively critical for the floor sweeping robot 200.

[0043] The roller brush cover 100 includes a cover body 10. The cover body 10 is used to be assembled on the housing, and a dust suction port 11 is formed on the cover body 10. The dust suction port 11 is used to expose the roller brush assembly 210, so that when the roller brush assembly 210 rotates, it contacts the ground through the dust suction port 11 for cleaning work. Among them, the cover body 10 has a first direction parallel to the axial direction of the roller brush assembly 210 (i.e. Figure 3The second direction perpendicular to the axial direction of the roller brush assembly 210 (i.e., in the longitudinal direction of the middle cover 10), and the third direction perpendicular to the first direction and the second direction (i.e., Figure 3 the thickness direction of the middle cover 10), and it can be understood that when the shape of the cover 10 changes, the first direction, the second direction and the third direction change accordingly, which is not limited here. Figure 3

[0044] Moreover, along the second direction, the cover 10 has an opposite inner side 15 and outer side 12. When the cover 10 is assembled on the housing, the outer side 12 of the cover 10 faces the ground, and the inner side 15 of the cover 10 faces the inside of the floor cleaning robot 200. The roller brush assembly 210 sucks the garbage on the external ground into the floor cleaning robot 200 inside the inner side 15 of the cover 10 through the dust suction port 11.

[0045] In some embodiments, an avoidance groove 13 is formed on the outer side 12 of the cover 10. The avoidance groove 13 is formed in the third direction, that is, the avoidance groove 13 is formed along the traveling direction perpendicular to the axial direction of the roller brush assembly 210. In this way, when the floor cleaning robot 200 works, the outer side 12 of the cover 10 faces the ground, and the floor cleaning robot 200 travels in the third direction perpendicular to the axial direction of the roller brush assembly 210. The extending direction of the avoidance groove 13 is the same as the traveling direction of the floor cleaning robot 200. During the traveling of the floor cleaning robot 200, the garbage on the ground can be misaligned with the avoidance groove 13, preventing the roller brush cover 100 from being lifted up after contacting the garbage on the ground, preventing a large gap from being generated between the roller brush cover 100 and the ground, ensuring that the floor cleaning robot 200 reliably adheres to the ground for dust suction and cleaning during the traveling process, and improving the dust suction and cleaning effect of the floor cleaning robot 200.

[0046] Furthermore, the avoidance groove 13 has an inlet 132 and an outlet 134 that communicate with each other in the third direction. In this way, when the floor cleaning robot 200 travels, the garbage on the ground can enter the avoidance groove 13 through the inlet 132 and then discharge from the outlet 134 of the avoidance groove 13, so that the garbage on the ground is avoided from the roller brush cover 100, preventing a large gap from being generated between the roller brush cover 100 and the ground after the roller brush cover 100 is lifted up by the garbage, and improving the dust suction and cleaning performance of the floor cleaning robot 200.

[0047] In some embodiments, along the first direction, the avoidance groove 13 has opposite first side wall 131 and second side wall; wherein, the first side wall 131 is located between the second side wall and the dust suction port 11; relative to the bottom wall of the avoidance groove 13, the second side wall is lower than the first side wall 131. Equivalently, the first side wall 131 on the side of the avoidance groove 13 close to the dust suction port 11 is higher, and the second side wall on the side of the avoidance groove 13 far from the dust suction port 11 and close to the side surface of the floor sweeping robot 200 is lower. Further equivalently, the distance between the first side wall 131 and the ground is relatively close, and the distance between the second side wall and the ground is relatively far, so as to form another channel under the second side wall of the avoidance groove 13. The garbage entering the avoidance groove 13 can be discharged through the outlet 134 of the avoidance groove 13 or discharged from under the second side wall, providing multiple channels for the garbage, making it more convenient for the roller brush cover 100 to avoid the garbage and further improving the cleaning effect.

[0048] Specifically, the cover body 10 includes a main body, a first guiding rib 16 and a second guiding rib 18. A dust suction port 11 is formed on the main body. Both the first guiding rib 16 and the second guiding rib 18 extend along the third direction, and the first guiding rib 16 and the second guiding rib 18 are arranged at intervals. An avoidance groove 13 is formed between the first guiding rib 16 and the second guiding rib 18. Equivalently, a dust suction port 11 is formed on the main body to expose the roller brush assembly 210, and the first guiding rib 16 and the second guiding rib 18 are arranged on the main body, and the avoidance groove 13 is formed by enclosing the first guiding rib 16 and the second guiding rib 18.

[0049] Further, the first guiding rib 16 is located between the second guiding rib 18 and the dust suction port 11; relative to the main body, the second guiding rib 18 is lower than the first guiding rib 16. Equivalently, the first guiding rib 16 is close to the dust suction port 11 inside the main body, and the second guiding rib 18 is close to the outer side 12 surface of the main body. And relative to the main body, the second guiding rib 18 is lower than the first guiding rib 16, the distance between the second guiding rib 18 and the ground is larger, and the distance between the first guiding rib 16 and the ground is smaller. An auxiliary channel communicating with the avoidance groove 13 can be formed between the second guiding rib 18 and the ground. In this way, when the floor sweeping robot 200 is moving forward, not only can the garbage be avoided and discharged through the avoidance groove 13, but also the garbage on the ground can be avoided and discharged through the auxiliary channel, providing multiple discharge paths for the garbage, improving the avoidance performance of the roller brush cover 100 and the garbage on the ground, and further improving the cleaning effect of the floor sweeping robot 200.

[0050] In some embodiments, the roller brush cover 100 further includes a guiding portion 30. Along a first direction parallel to the axial direction of the roller brush assembly 210, the guiding portion 30 has an opposite connection end 31 and a free end 33. The connection end 31 is connected to the cover body 10, and the free end is suspended and extends into the dust suction port 11. In the direction from the connection end 31 to the free end 33, the guiding portion 30 is inclined towards the inner side 15 of the cover body 10, that is, the guiding portion 30 is inclined towards the inside of the floor sweeping robot 200. In this way, the guiding portion 30 can guide the garbage around the dust suction port 11 to be sucked into the floor sweeping robot 200 under the action of the fan, preventing the two sides of the dust suction port 11 from being missed sucked, and further improving the cleaning performance and cleaning efficiency of the floor sweeping robot 200.

[0051] Further, along a third direction perpendicular to the first direction and the second direction, the outer side 12 of the cover body 10 has a first outer surface 121 and a second outer surface 123 located on both sides of the dust suction port 11. The first outer surface 121 and the second outer surface 123 are arranged with a vertical offset from each other, that is, one of the first outer surface 121 and the second outer surface 123 is higher than the other. In this way, when the cover body 10 is assembled on the housing and performs a cleaning operation towards the ground, the one of the first outer surface 121 and the second outer surface 123 that is relatively higher with respect to the ground is located in front of the traveling path, and the one of the first outer surface 121 and the second outer surface 123 that is relatively lower with respect to the ground is located behind the traveling path. Thus, during the traveling of the floor sweeping robot 200, the side of the roller brush cover 100 that is relatively higher with respect to the ground is in the front, and can first accommodate the garbage under the cover body 10 and adsorb it through the dust suction port 11. Then, the side of the roller brush cover 100 that is relatively lower with respect to the ground moves forward again. In this way, the garbage on the ground can be well guided into the dust suction port 11 below the floor sweeping robot 200, preventing the garbage on the ground from interfering with the roller brush cover 100 and affecting the cleaning effect of the floor sweeping robot 200. Optionally, the first outer surface 121 is lower than the second outer surface 123 relative to the dust suction port 11.

[0052] Specifically, the guiding portion 30 extends and connects between the first outer surface 121 and the second outer surface 123, guiding the garbage at the entire side end of the dust suction port 11 and comprehensively improving the cleaning effect. Specifically, the guiding portion 30 is recessed towards the inner side 15 of the cover body 10, so that the guiding portion 30 is transitionally connected between the first outer surface 121 and the second outer surface 123, and increases the space between the guiding portion 30 and the ground when the guiding portion 30 faces the ground, so as to improve the effect of guiding the garbage from the side.

[0053] Specifically in this embodiment, the guiding portion 30 includes a first connecting section 32, a second connecting section 34, and an intermediate section 36 connected between the first connecting section 32 and the second connecting section 34. The first connecting section 32 is connected between the first outer surface 121 and the intermediate section 36, and the second connecting section 34 is connected between the second outer surface 123 and the intermediate section 36. Among them, the intermediate section 36 is arranged offset from the first outer surface 121 and the second outer surface 123, and the intermediate section 36 is located inside the cover body 10, i.e., the inner side 15. Equivalently, the intermediate section 36 is arranged facing the inside of the floor cleaning robot 200 relative to the first outer surface 121 and the second outer surface 123, and the first outer surface 121 and the intermediate section 36 are connected through the first connecting section 32, and the second outer surface 123 and the intermediate section 36 are connected through the second connecting section 34. In this way, the guiding portion 30 as a whole is constructed to be recessed towards the inside of the cover body 10 to improve the effect of side suction of garbage.

[0054] Further, in the direction from the connecting end 31 to the free end 33, the first connecting section 32 is inclined towards the inner side 15 of the cover body 10, that is, the first connecting section 32 is inclined towards the inside of the floor cleaning robot 200 to guide the garbage on the side of the suction port 11 to be side-sucked into the floor cleaning robot 200. In the direction from the connecting end 31 to the free end 33, the second connecting section 34 is inclined towards the inner side 15 of the cover body 10, that is, the second connecting section 34 is inclined towards the inside of the floor cleaning robot 200 to guide the garbage on the side of the suction port 11 to be side-sucked into the floor cleaning robot 200. In the direction from the connecting end 31 to the free end 33, the intermediate section 36 is inclined towards the inner side 15 of the cover body 10, that is, the intermediate section 36 is inclined towards the inside of the floor cleaning robot 200 to guide the garbage on the side of the suction port 11 to be side-sucked into the floor cleaning robot 200, thereby improving the cleaning performance of the floor cleaning robot 200.

[0055] It can be understood that in some other embodiments, the guiding portion 30 can also be set as an arc-shaped plate, which is not limited herein.

[0056] In some embodiments, the suction port 11 has opposite first end 112 and second end 114, and the guiding portion 30 extending into the suction port 11 is provided at at least one of the first end 112 and the second end 114. In this way, the guiding portion 30 is provided on the side of the suction port 11 to improve the suction effect.

[0057] Understandably, in some embodiments, a guiding portion 30 is provided at the first end 112 of the dust suction port 11, and the guiding portion 30 can guide the side suction of garbage on one side of the first end 112 of the dust suction port 11. In some other embodiments, a guiding portion 30 is provided at the second end 114 of the dust suction port 11, and the guiding portion 30 can guide the side suction of garbage on one side of the cleaning second end 114. In some other embodiments, guiding portions 30 are provided at both the first end 112 and the second end 114 of the dust suction port 11, and the guiding portions 30 can guide the side suction of garbage on both sides of the first end 112 and the second end 114 of the dust suction port 11, improving the cleaning effect and cleaning efficiency of the floor sweeping robot 200.

[0058] In some embodiments, the guiding portion 30 is integrally formed with the cover body 10, and no other fitting parts are required to connect the guiding portion 30 and the cover body 10, simplifying the assembly process of the roller brush cover 100.

[0059] In some embodiments, along a first direction parallel to the axial direction of the roller brush assembly 210, the outer side 12 of the cover body 10 has a third outer surface 125 and a fourth outer surface 127 located on both sides of the dust suction port 11. The third outer surface 125 and / or the fourth outer surface 127 are provided with avoidance grooves 13, that is, the avoidance grooves 13 are provided on at least one side of the two sides of the cover body 10 in the first direction, so as to guide the garbage to be discharged from the avoidance grooves 13 from at least one side of the cover body 10, preventing the garbage from lifting the roller brush cover 100 and affecting the cleaning effect, and improving the dust suction and cleaning performance. In addition, the first outer surface 121 and the second outer surface 123 are both connected between the third outer surface 125 and the fourth outer surface 127, so that the first outer surface 121, the second outer surface 123, the third outer surface 125 and the fourth outer surface 127 enclose each other to form the dust suction port 11.

[0060] Further, along the third direction, both the third outer surface 125 and the fourth outer surface 127 have a lower side 128 and a higher side 129; relative to the dust suction port 11, the lower side 128 is lower than the higher side 129. That is, the third outer surface 125 and the fourth outer surface 127 are arranged in a high-low staggered manner in the third direction. When the floor cleaning robot 200 is working on the ground, the height between the lower side 128, which is relatively lower than the dust suction port 11, and the ground is higher, and the height between the higher side 129, which is relatively higher than the dust suction port 11, and the ground is lower. In this way, the lower side 128 is oriented towards the front of the traveling direction. When the floor cleaning robot 200 travels, the garbage can enter the avoidance groove 13 unobstructed from below the lower side 128 with a larger distance from the ground, and then the garbage can be discharged from the higher side 129 out of the avoidance groove 13. In this way, the garbage is guided into the avoidance groove 13, improving the cleaning effect. Optionally, the first outer surface 121 and the lower side 128 are on the same side, and the second outer surface 123 and the higher side 129 are on the same side. In this way, the whole roller brush cover 100 is higher on one side and lower on the other side in the third direction, facilitating the guiding of the garbage from the space between the lower side 128 and the ground into the dust suction port 11 and the avoidance groove 13.

[0061] Specifically, the bottom wall of the avoidance groove 13 includes a first bottom wall 135, a second bottom wall 137, and a third bottom wall 139. The first bottom wall 135 and the lower side 128 are on the same side, the second bottom wall 137 and the higher side 129 are on the same side, and the third bottom wall 139 is inclined to connect between the first bottom wall 135 and the second bottom wall 137. In this way, the bottom wall of the avoidance groove 13 is matched with the outer surface of the cover body 10 and is also set to be higher on one side and lower on the other side in the third direction, further facilitating the guiding of the garbage into the avoidance groove 13 and improving the overall dust suction and cleaning effect of the floor cleaning robot 200.

[0062] Based on the same concept, in an embodiment of the present invention, there is also provided a roller brush mechanism as described above. The roller brush mechanism includes a housing, a roller brush assembly 210, and a roller brush cover 100. The housing has an opening, the roller brush assembly 210 is disposed in the housing through the opening, and the roller brush cover 100 is covered at the opening and is engaged with the housing. In this way, an accommodation space is formed between the housing and the roller brush cover 100, and the roller brush assembly 210 is assembled in the accommodation space.

[0063] Moreover, an avoidance groove 13 is formed on the outer side 12 of the cover body 10, and the avoidance groove 13 is formed in a third direction perpendicular to the axial direction of the roller brush assembly 210. In this way, when the floor sweeping robot 200 is working, the outer side 12 of the cover body 10 faces the ground, and the floor sweeping robot 200 travels in a third direction perpendicular to the axial direction of the roller brush assembly 210. The extending direction of the avoidance groove 13 is the same as the traveling direction of the floor sweeping robot 200. During the traveling process of the floor sweeping robot 200, the garbage on the ground can be misaligned through the avoidance groove 13, preventing the roller brush cover 100 from being lifted up after contacting the garbage on the ground, preventing a large gap from being generated between the roller brush cover 100 and the ground, ensuring that the floor sweeping robot 200 can reliably adhere to the ground for dust suction and cleaning during the traveling process, and improving the dust suction and cleaning effect of the floor sweeping robot 200. In addition, a guiding portion 30 is provided on the roller brush cover 100, and the guiding portion 30 can guide the garbage around the dust suction port 11 to be laterally sucked into the interior of the floor sweeping robot 200, improving the cleaning effect and cleaning efficiency.

[0064] Based on the same concept, in an embodiment of the present invention, a roller brush cover 100 as described above is further provided. The roller brush cover 100 includes a cover body 10, and the cover body 10 is used for being assembled on the housing. A dust suction port 11 is formed on the cover body 10, and the dust suction port 11 is used for exposing the roller brush assembly 210, so that when the roller brush assembly 210 rotates, it contacts the ground through the dust suction port 11 for cleaning work. Moreover, along a second direction perpendicular to the axial direction of the roller brush assembly 210, the cover body 10 has opposite inner side 15 and outer side 12. When the cover body 10 is assembled on the housing, the outer side 12 of the cover body 10 faces the ground, and the inner side 15 of the cover body 10 faces the interior of the floor sweeping robot 200. The roller brush assembly 210 sucks the garbage on the external ground into the interior of the floor sweeping robot 200 on the inner side 15 of the cover body 10 through the dust suction port 11.

[0065] Moreover, an avoidance groove 13 is formed on the outer side 12 of the cover body 10, and the avoidance groove 13 is formed in a third direction perpendicular to the axial direction of the roller brush assembly 210. In this way, when the floor sweeping robot 200 is working, the outer side 12 of the cover body 10 faces the ground, and the floor sweeping robot 200 travels in a third direction perpendicular to the axial direction of the roller brush assembly 210. The extending direction of the avoidance groove 13 is the same as the traveling direction of the floor sweeping robot 200. During the traveling process of the floor sweeping robot 200, the garbage on the ground can be misaligned through the avoidance groove 13, preventing the roller brush cover 100 from being lifted up after contacting the garbage on the ground, preventing a large gap from being generated between the roller brush cover 100 and the ground, ensuring that the floor sweeping robot 200 can reliably adhere to the ground for dust suction and cleaning during the traveling process, and improving the dust suction and cleaning effect of the floor sweeping robot 200.

[0066] In addition, a guiding portion 30 is provided on the roller brush cover 100, and the guiding portion 30 can guide the garbage around the dust suction port 11 to be laterally sucked into the interior of the floor sweeping robot 200, improving the cleaning effect and cleaning efficiency.

[0067] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0068] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
