Description

Technical Field

[0001] This application relates to the field of clean technology, and more specifically, to a base station and a cleaning system. Background Technology

[0002] Robotic vacuum cleaners, mops, or floor scrubbers can automatically clean floors in a room using a certain level of artificial intelligence. A base station is a device that works in conjunction with the cleaning unit. The cleaning unit can use the base station to charge, clean the mop, and collect dust.

[0003] Currently, base stations typically have a cleaning tank for washing mops. A ramp with ribs is also installed on one side of the tank. The drive wheels at the bottom of the cleaning unit contact these ribs to increase friction between the cleaning unit and the ramp, allowing the cleaning unit to climb up the ramp and bring the mop into the cleaning tank. However, in actual use, due to factors such as the ramp's short length, steep slope, slipperiness, and the wetness of the drive wheels and mop, the cleaning unit easily slips on the ramp, preventing it from smoothly returning to the base station. Utility Model Content

[0004] The main objective of this application is to provide a base station and a cleaning system to solve the problem in the prior art where the cleaning host easily slips on the ramp when returning to the base station, causing the cleaning host to be unable to return to the base station smoothly.

[0005] According to one aspect of this application, a base station is provided, comprising:

[0006] main body;

[0007] A ramp is connected to the bottom of the main body. The ramp is provided with anti-slip components, which include a first anti-slip part and a second anti-slip part. The first anti-slip part is at least used to contact the drive wheel at the bottom of the cleaning unit. The second anti-slip part is at least used to apply auxiliary friction force to the cleaning unit when the cleaning component at the bottom of the cleaning unit rotates, so that the cleaning unit moves toward the main body.

[0008] Furthermore, the second anti-slip part includes:

[0009] A first rib is provided on the ramp plate. The first rib is at least used to contact the cleaning component when the cleaning component rotates, so as to apply a first frictional force to the cleaning component.

[0010] The second rib protrudes from the ramp plate and is at least used to contact the cleaning component when the cleaning component rotates, so as to apply a second frictional force to the cleaning component.

[0011] The direction of the resultant force of the first frictional force and the second frictional force is the same as the direction in which the cleaning host moves toward the main body.

[0012] Furthermore, the first rib is provided with a first friction surface for contacting the cleaning component, and the second rib is provided with a second friction surface for contacting the cleaning component. The first friction surface and the second friction surface are arranged symmetrically about the midline of the width direction of the ramp plate.

[0013] Furthermore, the first rib and the second rib are respectively disposed on both sides of the ramp slab in the width direction and are spaced at a predetermined distance from the center line;

[0014] The sides of the first and second friction surfaces that are away from each other are inclined toward the direction closer to the main body. Alternatively, the sides of the first and second friction surfaces that are close to each other are inclined toward the direction closer to the main body.

[0015] Furthermore, both the first rib and the second rib are positioned close to the center line;

[0016] The sides of the first friction surface and the second friction surface that are away from each other are inclined toward the direction of the main body; or, the sides of the first friction surface and the second friction surface that are close to each other are inclined toward the direction of the main body.

[0017] Furthermore, both the first rib and the second rib include multiple ribs, with the multiple first ribs arranged at intervals along the length direction of the ramp slab, and the multiple second ribs arranged at intervals along the length direction of the ramp slab.

[0018] Furthermore, both the first and second ribs have an inclined surface on the side away from the main body. The inclined surface is inclined towards the main body on the side away from the ramp plate, and the angle between the inclined surface and the upper surface of the ramp plate is an acute angle.

[0019] Furthermore, the first anti-slip portion includes at least two parts, and along the width direction of the ramp slab, at least two of the first anti-slip portions are respectively disposed on opposite sides of the second anti-slip portion.

[0020] Furthermore, each of the first anti-slip parts includes a protrusion, the protrusion being protruded from the ramp plate, and the protrusion height of the first rib and the protrusion height of the second rib are both less than the protrusion height of the protrusion.

[0021] On the other hand, this application also provides a cleaning system, comprising:

[0022] The aforementioned base station;

[0023] The cleaning host has a drive wheel and a cleaning component at its bottom. The cleaning component includes a first disc mop and a second disc mop. The first disc mop rotates in a first direction, and the second disc mop rotates in a second direction opposite to the first direction.

[0024] The cleaning host has a return state that moves along the ramp towards the main body. When the cleaning host is in the return state, the first anti-slip part contacts the drive wheel, and the first disc mop and the second disc mop descend to contact the ramp and rotate, so that the second anti-slip part contacts the cleaning component and applies auxiliary friction to the cleaning host.

[0025] In this application, when the cleaning unit returns to the main body, it travels along the upper surface of the ramp and moves closer to the main body. The drive wheel at the bottom of the cleaning unit contacts the first anti-slip part, which increases the friction between the cleaning unit and the ramp, reducing slippage. Simultaneously, the cleaning component at the bottom of the cleaning unit descends to contact the second anti-slip part and rotates relative to the ramp. The rotation of the cleaning component applies a force to the second anti-slip part, and according to the principle of action and reaction, the second anti-slip part simultaneously applies a reaction force to the cleaning component. This reaction force is the aforementioned auxiliary friction force, which promotes the cleaning unit's movement towards the main body, further reducing slippage and deviation. Even when the ramp is short, has a steep slope, is slippery, or the drive wheel and cleaning component at the bottom of the cleaning unit are wet, the cooperation of the first and second anti-slip parts ensures significant friction between the cleaning unit and the ramp, guaranteeing a smooth return to the main body and improving the user experience. With the cooperation of the first and second anti-slip parts, the second anti-slip part reduces the cleaning unit's need for longer, gentler ramps. The ramp length can be set to be shorter, and the ramp slope can be set to be greater, which is conducive to the development of ramps with a smaller footprint.

[0026] Additionally, when the cleaning unit moves from the ground onto the ramp, the cleaning components first contact the second anti-slip part. The second anti-slip part applies auxiliary friction to the cleaning unit, propelling it towards the main body and allowing the drive wheels of the cleaning unit to move smoothly onto the ramp. When the drive wheels slip and briefly suspend above the ramp, the auxiliary friction applied by the second anti-slip part effectively prevents the cleaning unit from slipping backward.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0042] See Figures 1 to 9 As shown, this application provides a base station 100. The base station 100 includes a main body 10 and a ramp 20. The ramp 20 is connected to the bottom of the main body 10. An anti-slip component 30 is provided on the ramp 20. The anti-slip component 30 includes a first anti-slip portion 31 and a second anti-slip portion 32. The first anti-slip portion 31 is at least used to contact the drive wheel 201 at the bottom of the cleaning host 200. The second anti-slip portion 32 is at least used to apply an auxiliary frictional force to the cleaning host 200 when the cleaning component 202 at the bottom of the cleaning host 200 rotates, so that the cleaning host 200 moves towards the main body 10.

[0043] In this embodiment, when the cleaning host 200 returns to the main body 10, it travels on the upper surface of the ramp 20 and moves closer to the main body 10. The drive wheel 201 at the bottom of the cleaning host 200 contacts the first anti-slip part 31, which increases the friction between the cleaning host 200 and the ramp 20, reducing slippage. Simultaneously, when the cleaning component 202 can be raised and lowered relative to the cleaning host 200, it descends to contact the second anti-slip part 32 and rotates relative to the ramp 20. When the cleaning component 202 cannot be raised or lowered, and the cleaning host 200 returns to the base station, it can directly contact the second anti-slip part 32 and rotate relative to the ramp 20. The rotation of the cleaning component 202 applies a force to the second anti-slip part 32, and according to the principle of action and reaction, the second anti-slip part 32 simultaneously applies a reaction force to the cleaning component 202. The reaction force is the aforementioned auxiliary friction force, which promotes the movement of the cleaning unit 200 towards the main body 10, further reducing the likelihood of slippage or deviation. Even when the ramp 20 is short, has a steep slope, is slippery, or the drive wheel 201 and cleaning components 202 at the bottom of the cleaning unit 200 are wet, the cleaning unit 200 and the ramp 20 can still have significant friction with the first anti-slip part 31 and the second anti-slip part 32, ensuring that the cleaning unit 200 can smoothly return to the main body 10, thus improving the user experience. With the cooperation of the first anti-slip part 31 and the second anti-slip part 32, the second anti-slip part 32 reduces the need for a longer, gentler ramp 20. The length of the ramp 20 can be set to be smaller, and the slope of the ramp 20 can be set to be greater, which is beneficial for reducing the footprint of the ramp 20.

[0044] Furthermore, when the cleaning unit 200 moves from the ground onto the ramp 20, the cleaning component 202 first contacts the second anti-slip part 32. The second anti-slip part 32 applies auxiliary friction to the cleaning unit 200, pushing it towards the main body 10, allowing the drive wheel 201 of the cleaning unit 200 to move smoothly onto the ramp 20. When the drive wheel 201 slips and briefly suspends itself on the ramp 20, the auxiliary friction applied by the second anti-slip part 32 effectively prevents the cleaning unit 200 from slipping backward.

[0045] like Figures 1 to 3As shown, in one embodiment, the second anti-slip part 32 includes a first rib 321 and a second rib 322. The first rib 321 protrudes from the ramp 20. The first rib 321 is at least used to contact the cleaning component 202 when it rotates, so as to apply a first frictional force F1 to the cleaning component 202. The second rib 322 protrudes from the ramp 20. The second rib 322 is at least used to contact the cleaning component 202 when it rotates, so as to apply a second frictional force F2 to the cleaning component 202. The direction of the resultant force of the first frictional force F1 and the second frictional force F2 is the same as the direction of movement of the cleaning host 200 towards the body 10. The resultant force of the first frictional force F1 and the second frictional force F2 forms the aforementioned auxiliary frictional force, and the direction of the resultant force is the same as the direction of movement of the cleaning host 200 towards the body 10. Therefore, the first rib 321 and the second rib 322 can convert the rotational power of the cleaning component 202 into an auxiliary frictional force that pushes the cleaning host 200 towards the body 10. In other words, the first anti-slip part 31 and the second anti-slip part 32 work together to further enhance the driving assistance to the cleaning host 200, effectively reduce the possibility of the cleaning host 200 slipping, and ensure that the cleaning host 200 can return to the main body 10 smoothly.

[0046] Among them, such as Figure 4 As shown, the first rib 321 is provided with a first friction surface 3211 for contacting the cleaning component 202. The second rib 322 is provided with a second friction surface 3221 for contacting the cleaning component 202. The first friction surface 3211 and the second friction surface 3221 are related to the width direction of the ramp 20 (e.g., ...). Figure 1 The cleaning components are symmetrically arranged along the midline Q (in the direction indicated by the middle arrow X). When the cleaning component 202 rotates and contacts the first rib 321 and the second rib 322, the first friction surface 3211 of the first rib 321 applies a first frictional force F1 to the cleaning host 200, and the second friction surface 3221 of the second rib 322 applies a second frictional force F2 to the cleaning host 200. Since the first friction surface 3211 and the second friction surface 3221 are symmetrically arranged about the midline Q of the ramp 20 width direction, the components of the first frictional force F1 and the second frictional force F2 in the ramp 20 width direction cancel each other out, while the components in the direction of movement of the cleaning host 200 toward the main body 10 are superimposed to form a large resultant force that pushes the cleaning host 200 toward the main body 10, ensuring that the cleaning host 200 can smoothly return to the main body 10.

[0047] Specifically, the cleaning component 202 includes a first disc mop 2021 and a second disc mop 2022. The first disc mop 2021 and the second disc mop 2022 are symmetrically arranged about the center line Q. The first disc mop 2021 is positioned opposite to the first rib 321, and the second disc mop 2022 is positioned opposite to the second rib 322. During the movement of the cleaning host 200 toward the main body 10, the first friction surface 3211 applies a first frictional force F1 to the first disc mop 2021, and the second friction surface 3221 applies a second frictional force F2 to the second disc mop 2022. The symmetrically arranged first friction surface 3211 and second friction surface 3221 cancel out the components of the first frictional force F1 and the second frictional force F2 in the width direction, effectively preventing the first disc mop 2021 and the second disc mop 2022 from shifting due to uneven force, and ensuring that the cleaning host 200 moves along the length direction of the ramp 20 (e.g., Figure 1 Move in the direction indicated by the middle arrow Y.

[0048] In actual use, when the cleaning host 200 moves from the ground onto the ramp 20, the first disc mop 2021 and the second disc mop 2022 will rotate at different speeds, causing the cleaning host 200 to deviate along the width direction of the ramp 20. To reduce the deviance of the cleaning host 200, the components of the first friction force F1 and the second friction force F2 in the width direction of the ramp 20 in this embodiment can effectively counteract the deviance of the cleaning host 200, dynamically adjust the amount of deviance of the cleaning host 200 in the width direction of the ramp 20, and reduce the deviance of the cleaning host 200, so that the cleaning host 200 moves towards the main body 10 along the length direction of the ramp 20, ensuring that the cleaning host 200 can smoothly return to the main body 10.

[0049] The first disc mop 2021 moves along the first direction (e.g.) Figure 1 The second disc mop 2022 rotates in the direction indicated by the middle arrow M (in this embodiment, the first direction is counterclockwise). The second disc mop 2022 rotates in the direction corresponding to the second direction (e.g., ...). Figure 1 The direction indicated by the middle arrow N (in this embodiment, the second direction is clockwise) is the rotation. The first direction is opposite to the second direction.

[0050] like Figure 5As shown, when the first disc mop 2021 rotates along a first direction and the second disc mop 2022 rotates along a second direction, in one embodiment, the first rib 321 and the second rib 322 are respectively disposed on both sides of the ramp 20 in the width direction and spaced a predetermined distance from the center line Q. The sides of the first friction surface 3211 and the second friction surface 3221 that are away from each other are inclined towards the main body 10. When the cleaning host 200 is on the ramp 20, the first friction surface 3211 applies a first frictional force F1 to the first disc, which is inclined towards the main body 10 and towards the second disc mop 2022. The second friction surface 3221 applies a second frictional force F2 to the second disc, which is inclined towards the main body 10 and towards the first disc mop 2021. The components of the first frictional force F1 and the second frictional force F2 in the width direction of the ramp 20 can cancel each other out. The first frictional force F1 and the second frictional force F2 can also reduce the offset caused by the different rotation speeds of the first disc mop 2021 and the second disc mop 2022. The components of the first frictional force F1 and the second frictional force F2 along the length of the ramp slab 20 can be superimposed. The direction of the resultant force is along the length of the ramp slab 20 towards the side of the main body 10, so as to drive the cleaning host 200 towards the main body 10, increase the return power of the cleaning host 200, and ensure that the cleaning host 200 can return to the main body 10 smoothly.

[0051] like Figure 9 As shown, preferably, the first frictional force F1 is perpendicular to the first friction surface 3211, and the second friction surface 3221 is perpendicular to the second friction surface 3221. In the height direction of the main body 10 (e.g., ... Figure 1 Within the projection of the direction indicated by the middle arrow Z, the angle between the first friction surface 3211 and the width direction of the ramp 20 is A, which satisfies the relationship: 25°≤A≤60°. The second friction surface 3221 and the first friction surface 3211 are symmetrically arranged about the main body 10, and A can be set to one of 25°, 30°, 35°, 40°, 45°, 50°, 55°, or 60°. The first friction force F1 and the second friction force F2 can effectively increase the power of the cleaning host 200 to move towards the main body 10, and can also reduce the offset of the cleaning host 200. If A < 25°, the resultant force of the first friction force F1 and the second friction force F2 in the length direction of the ramp 20 is small and cannot effectively correct the offset of the cleaning host 200. If A > 60°, the resultant force of the first friction force F1 and the second friction force F2 in the width direction of the ramp 20 is small and cannot meet the requirement of assisting the cleaning host 200.

[0052] like Figure 6As shown, in another embodiment, the first rib 321 and the second rib 322 are respectively disposed on both sides of the ramp 20 in the width direction and spaced a predetermined distance from the center line Q. The first friction surface 3211 and the second friction surface 3221 are inclined towards the main body 10 on the side closest to each other. When the cleaning host 200 is on the ramp 20, the first friction surface 3211 applies a first frictional force F1 to the first disc towards the main body 10 and inclined away from the second disc mop 2022, and the second friction surface 3221 applies a second frictional force F2 to the second disc towards the main body 10 and inclined away from the first disc mop 2021. The components of the first frictional force F1 and the second frictional force F2 in the width direction of the ramp 20 can cancel each other out. The first frictional force F1 and the second frictional force F2 can also reduce the offset caused by the different rotation speeds of the first disc mop 2021 and the second disc mop 2022. The components of the first frictional force F1 and the second frictional force F2 along the length of the ramp slab 20 can be superimposed. The direction of the resultant force is along the length of the ramp slab 20 towards the side of the main body 10, so as to drive the cleaning host 200 towards the main body 10, increase the return power of the cleaning host 200, and ensure that the cleaning host 200 can return to the main body 10 smoothly.

[0053] In the two embodiments described above, the first rib 321 and the second rib 322 are respectively spaced at a predetermined distance from the center line. This means that the first rib 321 is located on the side of the center of the first disc mop 2021 away from the second rib 322, and the second rib 322 is located on the side of the center of the second disc mop 2022 away from the first rib 321.

[0054] like Figure 7As shown, when the first disc mop 2021 rotates in the second direction and the second disc mop 2022 rotates in the first direction, in one embodiment, both the first rib 321 and the second rib 322 are positioned close to the center line Q, and the sides of the first friction surface 3211 and the second friction surface 3221 that are away from each other are inclined towards the main body 10. When the cleaning host 200 is on the ramp 20, the first friction surface 3211 applies a first frictional force F1 to the first disc, which is directed towards the main body 10 and inclined towards the second disc mop 2022, and the second friction surface 3221 applies a second frictional force F2 to the second disc, which is directed towards the main body 10 and inclined towards the first disc mop 2021. The components of the first frictional force F1 and the second frictional force F2 in the width direction of the ramp 20 can cancel each other out, and the first frictional force F1 and the second frictional force F2 can also reduce the offset caused by the different rotation speeds of the first disc mop 2021 and the second disc mop 2022. The components of the first frictional force F1 and the second frictional force F2 along the length of the ramp slab 20 can be superimposed. The direction of the resultant force is along the length of the ramp slab 20 towards the side of the main body 10, so as to drive the cleaning host 200 towards the main body 10, increase the return power of the cleaning host 200, and ensure that the cleaning host 200 can return to the main body 10 smoothly.

[0055] like Figure 8 As shown, in another embodiment, both the first rib 321 and the second rib 322 are positioned close to the center line Q, and the first friction surface 3211 and the second friction surface 3221 are inclined towards the body 10 on the side closest to each other. When the cleaning host 200 is on the ramp 20, the first friction surface 3211 applies a first frictional force F1 to the first disc, which is directed towards the body 10 and inclined away from the second disc mop 2022, and the second friction surface 3221 applies a second frictional force F2 to the second disc, which is directed towards the body 10 and inclined away from the first disc mop 2021. The components of the first frictional force F1 and the second frictional force F2 in the width direction of the ramp 20 can cancel each other out, and the first frictional force F1 and the second frictional force F2 can also reduce the offset caused by the different rotation speeds of the first disc mop 2021 and the second disc mop 2022. The components of the first frictional force F1 and the second frictional force F2 along the length of the ramp slab 20 can be superimposed. The direction of the resultant force is along the length of the ramp slab 20 towards the side of the main body 10, so as to drive the cleaning host 200 towards the main body 10, increase the return power of the cleaning host 200, and ensure that the cleaning host 200 can return to the main body 10 smoothly.

[0056] In both embodiments described above, the first rib 321 and the second rib 322 are both positioned close to the center line. Specifically, the first rib 321 is located on the side of the center of the first disc mop 2021 closest to the second rib 322, and the second rib 322 is located on the side of the center of the second disc mop 2022 closest to the first rib 321. The first rib 321 and the second rib 322 can be connected to each other or arranged at intervals.

[0057] In another embodiment, the first friction surface 3211 and the second friction surface 3221 are both parallel to the width direction of the ramp 20. The first friction surface 3211 and the second friction surface 3221 can also increase the friction between the mop and the ramp 20 to prevent the cleaning host 200 from slipping or sliding backward.

[0058] In one embodiment, multiple first ribs 321 and multiple second ribs 322 are included. Multiple first ribs 321 are spaced apart along the length of the ramp 20. Multiple second ribs 322 are spaced apart along the length of the ramp 20. When the cleaning host 200 moves along the ramp 20 toward the main body 10, the cleaning component 202 rotating at the bottom of the cleaning host 200 will sequentially contact the spaced-apart first ribs 321 and multiple second ribs 322 as the cleaning host 200 moves. The first friction surface 3211 of each first rib 321 contacts the cleaning component 202, generating a first frictional force F1 obliquely toward the main body 10. The second friction surface 3221 of each second rib 322 contacts the cleaning component 202, generating a second frictional force F2 obliquely toward the main body 10. The components of the first frictional force F1 and the second frictional force F2 at each corresponding position cancel each other out in the width direction of the ramp 20, and the components in the length direction of the ramp 20 are superimposed, resulting in a resultant force continuously pointing toward the main body 10. Throughout the entire process of the cleaning unit 200 climbing, the first rib 321 and the second rib 322 continuously contact the rotating cleaning component 202 and provide auxiliary friction, making the auxiliary friction more consistent and stable in propelling the cleaning unit 200 to move. Simultaneously, the combined force of multiple first ribs 321 and multiple second ribs 322 has a stronger effect, which, combined with the anti-slip function of the first anti-slip part 31 on the drive wheel 201, further reduces the possibility of the cleaning unit 200 slipping, ensuring that the cleaning unit 200 smoothly and steadily returns to the main body 10.

[0059] The first ribs 321 are arranged at intervals and evenly along the length of the ramp slab 20, and the second ribs 322 are arranged at intervals and evenly along the length of the ramp slab 20. The first ribs 321 and the second ribs 322 can provide a uniform and stable auxiliary friction force to the cleaning host 200, and also facilitate the processing and manufacturing of the first ribs 321 and the second ribs 322.

[0060] In one embodiment, both the first rib 321 and the second rib 322 have an inclined surface 325 on the side away from the main body 10. The inclined surface 325 is inclined towards the main body 10 on the side away from the ramp 20, and the angle between the inclined surface 325 and the upper surface of the ramp 20 is an acute angle. The inclined surface 325 of the first rib 321 and the first friction surface 3211 are respectively located on opposite sides of the first rib 321, and the inclined surface 325 of the second rib 322 and the second friction surface 3221 are respectively located on opposite sides of the second rib 322. When the cleaning component 202 rotates to contact the inclined surface 325, the direction of the frictional force applied by the inclined surface 325 of the first rib 321 to the cleaning component 202 is away from the main body 10, and the direction of the frictional force applied by the inclined surface 325 of the second rib 322 to the cleaning component 202 is also away from the main body 10. The inclined surfaces 325 of the first rib 321 and the second rib 322 hinder the cleaning unit 200 from moving towards the main body 10. In this embodiment, the angle between the inclined surface 325 and the upper surface of the ramp 20 is an acute angle, so that the frictional force exerted by the inclined surface 325 of the first rib 321 on the cleaning component 202 is less than the first frictional force F1, and the frictional force exerted by the inclined surface 325 of the second rib 322 on the cleaning component 202 is less than the second frictional force F2. This ensures that the resultant force of the forces exerted by the first rib 321 and the second rib 322 on the cleaning component 202 is directed towards the main body 10, ensuring that the cleaning unit 200 can smoothly return to the main body 10. The inclined surface 325 can reduce the contact area between the cleaning component 202 and the first rib 321 and the second rib 322, guiding the cleaning component 202 to slide more smoothly over the first rib 321 and the second rib 322, reducing the obstructive effect of the inclined surface 325 on the cleaning component 202.

[0061] The inclined surface 325 can be partially planar and partially curved. When the inclined surface 325 is planar, the angle between the inclined surface 325 and the upper surface of the ramp 20 is acute. When the inclined surface 325 is curved, the angle between the inclined surface 325 and the upper surface of the ramp 20 is: the angle between the tangent at any point on the inclined surface 325 and the upper surface of the ramp 20 is acute. That is, in the thickness direction section at any point of the first rib 321 and the second rib 322, the angle between the line connecting the inclined surface 325 and the ramp 20 to any point within the inclined surface 325 and the upper surface of the ramp 20 is acute.

[0062] Specifically, taking the inclined surface 325 of the first rib 321 as an example, the inclined surface 325 of the first rib 321 includes a first inclined segment 3251, a second inclined segment 3252, and a third inclined segment 3253 connected in sequence. The first inclined segment 3251 is connected to the first side of the first friction surface 3211, and the third inclined segment 3253 is connected to the second side of the first friction surface 3211 opposite to the first side. The second inclined segment 3252 is a plane, while the first inclined segment 3251 and the third inclined segment 3253 are curved surfaces. Furthermore, the connection points between the first inclined segment 3251 and the second inclined segment 3252, and between the second inclined segment 3252 and the third inclined segment 3253, are smooth and gentle. Also, the angle between the portion of the first inclined segment 3251 and the third inclined segment 3253 that first contacts the cleaning component 202 and the upper surface of the ramp 20 is smaller. The second rib 322 and the first rib 321 are symmetrical about the midline Q.

[0063] In one embodiment, the first anti-slip portion 31 includes at least two. Along the width direction of the ramp 20, at least two first anti-slip portions 31 are respectively disposed on opposite sides of the second anti-slip portion 32. When the cleaning host 200 moves toward the main body 10, the drive wheels 201 located on both sides of the cleaning component 202 come into contact with the first anti-slip portions 31. The first anti-slip portions 31 can apply frictional force to the drive wheels 201 on both sides respectively, reducing slippage of the drive wheels 201.

[0064] In one embodiment, each of the first anti-slip portions 31 includes a protrusion 311. The protrusion 311 protrudes from the ramp 20. The protrusion height of the first rib 321 and the protrusion height of the second rib 322 are both less than the protrusion height of the protrusion 311. When the cleaning host 200 deviates, the protrusion can prevent the cleaning host 200 from swaying left and right and limit the deviation range of the cleaning component 202, which helps to correct the movement trajectory of the cleaning component 202 and make the cleaning host 200 move towards the main body 10.

[0065] The main body 10 has a receiving cavity. When the cleaning unit 200 moves into the receiving cavity, the cleaning component 202 is located in the cleaning tank 211 within the receiving cavity. The ramp 20 is connected to the bottom of the main body 10 and forms the aforementioned receiving cavity together with the main body 10.

[0066] On the other hand, this application also provides a cleaning system. The cleaning system includes a base station 100 and a cleaning host 200. The bottom of the cleaning host 200 is provided with a drive wheel 201 and a cleaning component 202. The cleaning component 202 includes a first disc mop 2021 and a second disc mop 2022. The first disc mop 2021 rotates in a first direction, and the second disc mop 2022 rotates in a second direction opposite to the first direction. The cleaning host 200 has a return-to-station state where it moves along the ramp 20 towards the main body 10. When the cleaning host 200 is in the return-to-station state, a first anti-slip part 31 contacts the drive wheel 201, and the first disc mop 2021 and the second disc mop 2022 descend to contact the ramp 20 and rotate, so that the second anti-slip part 32 applies an auxiliary frictional force to the cleaning host 200. The bottom of both the first disc mop 2021 and the second disc mop 2022 is provided with multiple strip-shaped structures. These strip-shaped structures can be embedded between multiple first ribs 321 and multiple second ribs 322, so that the second anti-slip part 32 applies auxiliary friction force to the cleaning host 200. The bottom of the first disc mop 2021 and the second disc mop 2022 is made of chenille material. This cleaning system includes all the technical effects of the base station 100 described above. Since the technical effects of the base station 100 have been described in detail above, they will not be repeated here.

[0067] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0068] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0069] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
