For example, a laundry detergent can be stacked on top of a floor cleaning device to reduce the space occupied by the appliances. However, this combination may negatively impact the daily user experience of the floor cleaning device. Utility Model Content

[0054] 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 one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly 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, an electrical connection, or a connection that allows communication between components; 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 expressly limited.

[0059] With continuous technological advancements, home appliances with various cleaning functions are emerging, such as robotic vacuum cleaners and robotic vacuum-mop systems that combine sweeping and mopping. However, these appliances require space, and placing multiple appliances individually can make a home feel cramped. To reduce the space occupied by these appliances and improve space utilization, related technologies are increasingly combining cleaning devices with different functions. For example, washing machines and dryers can be stacked, or space can be reserved at the bottom of washing machines (or dryers), air purifiers, etc., to accommodate cleaning stations that work with floor cleaning devices (such as robotic vacuum cleaners and robotic mops). Taking the washing machine and cleaning station combination as an example, the ease of cleaning and maintaining the cleaning station is affected by the washing machine, which in turn impacts the user's ability to perform daily cleaning and maintenance, and consequently affects the user's daily experience.

[0060] To address the aforementioned issues, this application provides a ramp 10, a cleaning device 100, and a cleaning system 1000. By detachably connecting the ramp 10 to the frame structure of the cleaning device 100, users can easily remove the ramp 10 from the frame of the cleaning device 100, reducing the difficulty of daily cleaning and maintenance of the ramp 10 and thus improving the user experience.

[0061] Figure 1 This is a partial structural diagram of the cleaning system 1000 provided in an embodiment of this application. Figure 2 This is a partial structural schematic diagram of the cleaning equipment 100 provided in an embodiment of this application. Figure 3 This is a schematic diagram of the internal structure of the cleaning device 100 provided in an embodiment of this application.

[0062] For ease of description, in this application embodiment, the height direction of the cleaning system 1000 at its upper and lower ends is defined as the first direction X (i.e., the X-axis direction), the direction of the cleaning system 1000 on the front and rear sides is defined as the second direction Y (i.e., the Y-axis direction), and the direction of the cleaning system 1000 on the left and right sides is defined as the third direction Z (i.e., the Z-axis direction), wherein the X-axis direction, the Y-axis direction, and the Z-axis direction are mutually perpendicular.

[0063] Please see Figure 1 and Figure 2 This application provides a cleaning system 1000 and a cleaning device 100. The cleaning system 1000 includes a cleaning device 100 and a floor cleaning unit 200 that cooperates with the cleaning device 100. The bottom of the cleaning device 100 has a space for accommodating a ramp 10 and the floor cleaning unit 200. The floor cleaning unit 200 can be parked on the bottom of the cleaning device 100 via the ramp 10 and can move in and out of the cleaning device 100 by traveling along the surface of the ramp 10, thereby cooperating with the cleaning device 100. Please refer to [link to relevant documentation]. Figure 2 The cleaning device 100 has a box-like structure. The drum 30 for handling clothes and the base station module 40 for cooperating with the floor cleaning host 200 are both located within this box-like structure. The drum 30 can be a washing drum for washing clothes, a drying drum for drying clothes, or a drum 30 that combines washing and drying functions. The base station module 40 has a mounting opening 401 for installing a ramp 10. When the ramp 10 is installed inside the cleaning device 100, the floor cleaning host 200 can cooperate with the base station module 40 and can park itself above the ramp 10 through the mounting opening 401, or move in and out of the cleaning device 100. This embodiment does not limit the clothing handling function of the cleaning device 100; that is, the clothing handling function of the cleaning device 100 can have washing and / or drying functions and / or both washing and drying functions simultaneously.

[0064] It should be noted that the overall size of the cleaning device 100 provided in this application embodiment is basically the same as that of existing conventional clothing processing devices, especially its size in the first direction X. In other words, the cleaning device 100 provided in this application embodiment can achieve the effect of simultaneously arranging the cylinder 30 and the base station module 40 inside the box without increasing or significantly increasing its height. This saves the space occupied by the cleaning device 100 in the user's home while effectively improving the overall stability, reliability and safety of the cleaning device 100.

[0065] The cleaning device 100 has a front door panel 50 on its front side in the second direction Y, and the front door panel 50 has a loading / unloading port 501 that cooperates with the cylinder 30. Clothes can be put into or taken out of the cylinder 30 through the loading / unloading port 501; the cleaning device 100 also includes a first door (not shown in the figure), which cooperates with the front door panel 50 and opens or closes the loading / unloading port 501 by moving relative to the front door panel 50. The base station module 40 is located below the cylinder 30 and forms a receiving space that can be exposed relative to the front door panel 50.

[0066] When the ground cleaning host 200 starts working, it can start from the storage space of the base station module 40 and perform the corresponding cleaning task. When the ground cleaning host 200 completes the cleaning task or other situations require the cleaning task to be stopped, the ground cleaning host 200 can return to the storage space of the base station module 40 to perform at least one or more of the following tasks: charging, water replenishment, cleaning, dust collection, etc.

[0067] The floor cleaning host 200 can be at least one of the following: a sweeping robot, a mopping robot, a floor washing robot, or a sweeping and mopping robot.

[0068] Please see Figure 3 The cleaning equipment 100 has a accommodating space for simultaneously accommodating the cylinder 30 and the base station module 40. The cleaning equipment 100 also includes a base 20 for fixing the base station module 40. The cylinder 30 and the base station module 40 are arranged sequentially in the accommodating space along the first direction X, with the cylinder 30 located above the base station module 40. The ramp plate 10 is located between the base 20 and the base station module 40 and is connected to the base 20.

[0069] The ramp 10 located between the base 20 and the base station can be connected to the base 20 via a plug-in connection, allowing users to easily install and remove the ramp 10 as needed. For example, when the ramp 10 accumulates dust, hair, or other debris due to repeated driving, stopping, and cleaning operations by the ground cleaning host 200, the user can remove the ramp 10 from the base 20 for cleaning. Afterward, the user can easily reinstall the cleaned ramp 10 onto the base 20 of the cleaning equipment 100.

[0070] Figure 4 This is a schematic diagram of the structure of the ramp 10 provided in the embodiments of this application. Figure 5 This is a schematic diagram of the ramp slab 10 provided in an embodiment of this application from another angle. Figure 6 Figure 5 Enlarged view of the structure of the S-region.

[0071] Please see Figure 4 and Figure 5 The ramp 10 includes a plate body 1 and at least one plug-in structure. The plate body 1 has a walking area 101 on its upper surface in the first direction X, and a plug-in structure is provided on its lower surface in the first direction X. The plug-in structure includes a slot 2. The plug-in structure is detachably connected to the base 20 to realize the quick-release function of the ramp 10.

[0072] Specifically, the walking area 101 is set on the upper surface of the plate 1 along the second direction Y. When the ground cleaning host 200 walks on the ramp 10 along the length of the walking area 101, it can move in and out relative to the cleaning equipment 100, so as to guide the ground cleaning host 200 to smoothly go up or down the pile.

[0073] In some embodiments, the upper surface of the plate 1 may also have a cleaning area 102, which may be located on one side of the walking area 101 in its extending direction, so as to facilitate the floor cleaning equipment 100 to perform cleaning operations through the cleaning area 102. The shape of the cleaning area 102 can be adjusted according to the shape of the structure to be cleaned on the floor cleaning equipment 100. Taking the floor cleaning equipment 100 with a disc mop as an example, the cleaning area 102 can be a structure adapted to the shape of the disc mop. When the floor cleaning equipment 100 has a semi-circular mop, the cleaning area 102 can be a structure adapted to the shape of the semi-circular mop.

[0074] For details, please refer to Figure 4 The cleaning area 102 is located at one end of the walking area 101 in the second direction Y. When the ramp 10 is installed on the base 20, the cleaning area 102 is located above the base 20. The walking area 101 can be located entirely above the base 20, or partially above the base 20, with part of it extending out relative to the base 20 in the second direction Y.

[0075] In this embodiment, the slot 2 is located at the bottom of the plate 1 in the first direction X, that is, on the lower surface of the plate 1. Each slot 2 has an opening 21 for engaging with the base 20. The opening 21 of the slot 2 is parallel to the mounting plane of the plate 1, so that the plate 1 can be inserted and engaged with the base 20 through the slot 2.

[0076] Specifically, the plate 1 is inserted into the base 20 along the second direction Y and is engaged with the base 20. At this time, the mounting plane of the plate 1 is parallel to the second direction Y. Correspondingly, the opening 21 of the slot 2 is also parallel to the second direction Y and points towards the base 20.

[0077] When installing the ramp plate 10 onto the base 20, the ramp plate 10 can be placed on the base 20 so that the bottom surface of the ramp plate 10 contacts the upper surface of the base 20. Then, a pushing force is applied to the ramp plate 10, causing it to gradually insert into the base 20 along the second direction Y. During this process, the slot 2 provided on the ground of the ramp plate 10 can be fixed by the insertion and engagement structure on the base 20 corresponding to the opening 21, thus completing the installation of the ramp plate 10 and the base 20. When it is necessary to remove the ramp plate 10 from the base 20, simply apply a pulling force opposite to the insertion direction to the ramp plate 10. At this time, the ramp plate 10 can overcome the frictional force to release the insertion and engagement with the base 20 and separate from the base 20.

[0078] The above structure does not require additional unlocking operations, which can effectively reduce the difficulty of disassembling and assembling the ramp plate 10 and the base 20.

[0079] To improve the firmness and stability of the connection between the ramp plate 10 and the base 20, the number of the aforementioned slots 2 is multiple and can be distributed along the second direction Y and / or the third direction Z on the lower surface of the plate body 1.

[0080] For details, please refer to Figure 5 The number of slots 2 is six. Two slots 2 are spaced apart along the second direction Y on the lower surface of the plate 1 at one end for inserting the cleaning device 100. The remaining four slots are arranged in pairs on both sides of the lower surface of the plate 1 along the third direction Z and are also spaced apart along the second direction Y. Of course, the number of slots 2 can be adjusted to be more or less. This embodiment does not limit the actual number and distribution of slots 2.

[0081] It should be noted that the insertion structure can also be set in other positions of the board body 1. For example, the board body 1 can be provided with the aforementioned slot 2 on the left and / or right sides in the third direction Z. When the board body 1 is inserted and engaged with the base 20 in the second direction Y, the slot 2 located on at least one side in the third direction Z of the board body 1 also has an opening 21 facing the second direction Y and can be inserted and fixed with the insertion and engagement structure set at the corresponding position of the base 20 as the board body 1 moves. Of course, the board body 1 can also be provided with a slot 2 on the upper surface in the first direction X. In this case, the insertion and engagement structure for engaging with the slot 2 can be formed on the base station module 40. When the board body 1 is inserted and engaged with the base 20 in the second direction Y, the slot 2 located on the upper surface of the board body 1 can also be inserted and engaged with the insertion and engagement structure set at the corresponding position of the base station module 40 as the board body 1 moves.

[0082] It is understood that the above-mentioned plug-in mating structure can be a block-shaped, strip-shaped, or other structure that mates with the socket of slot 2.

[0083] In some embodiments, the plate 1 and the slot 2 are integrally formed.

[0084] Please see Figure 5 and Figure 6 The back side of the plate 1 is provided with a slot 2, so when the ramp plate 10 is connected to the base 20, the plate 1 can be connected to the base 20 through the slot 2, and at least a part of the plate 1 is located above the base 20. When the dimension of the ramp plate 10 in the second direction Y is larger than the dimension of the base 20 in the second direction Y, a part of the plate 1 can extend relative to the base 20 and be located outside the base 20.

[0085] In this embodiment, the ramp 10 has a larger dimension in the second direction Y than the base 20 in the second direction Y, such that a portion of the plate 1 is located above the base 20, and the plate 1 protrudes relative to the base 20 in the second direction Y, with a portion of the plate 1 located outside the base 20. At this time, in the first direction X, the orthographic projection of the ramp 10 mounted on the base 20 in the first direction X at least partially coincides with the orthographic projection of the base 20 in the first direction X, and the orthographic projection of the plate 1 located outside the base 20 in the first direction X is exactly connected to the orthographic projection of the base 20 in the first direction X, with a partial overlap of the outer contour of the orthographic projection.

[0086] Since the ramp 10 is needed to guide the ground cleaning host 200 to climb up the walking area 101 on its upper surface to enter the cleaning equipment 100, in order to avoid the gap between the plate 1 and the mounting surface where the base 20 is placed being too large due to the influence of the base 20, the side of the plate 1 facing away from the walking area 101 is provided with a stepped surface 103.

[0087] Please see Figure 6The step surface 103 includes a first surface 1031, a second surface 1032, and a step sidewall 1033. The first surface 1031 is used to contact the base 20, the second surface 1032 is used to contact the mounting surface or be as close as possible to the mounting surface, and the step sidewall 1033 connects the first surface 1031 and the second surface 1032. The step surface 103 helps to reduce the gap between the ramp plate 10 and the mounting surface relative to the protruding portion of the base 20, thus reducing the difficulty of the floor cleaning unit 200 climbing the ramp.

[0088] When the ramp 10 is installed on the base 20 and the base 20 is placed on the mounting surface, the step sidewall 1033 extends along the first direction X and its two ends in the first direction X are respectively connected to the first surface 1031 and the second surface 1032. The second surface 1032 is located below the first surface 1031 for approaching or contacting the mounting surface.

[0089] Specifically, the second surface 1032 is located outside the base 20 and fits exactly against the mounting surface, or the gap between the second surface 1032 and the mounting surface will not affect the normal travel of the ground cleaning host 200 along the walking area 101 of the ramp 10.

[0090] For example, the gap formed between the second surface 1032 and the mounting surface can be set to be less than or equal to 3 mm.

[0091] It should be noted that the first surface 1031 and the second surface 1032 formed on the plate 1 can remain parallel or approximately parallel.

[0092] The specific structure of slot 2 is described below.

[0093] Figure 7 This is a top view of the ramp 10 provided in an embodiment of this application. Figure 8 for Figure 7 Sectional view along line AA in the middle, Figure 9 for Figure 8 Enlarged view of the structure of region B in the middle. Figure 10 for Figure 8 Enlarged view of the structure of region C in the middle. Figure 11 for Figure 7 BB-direction sectional view.

[0094] Plate 1 can be composed of two different plate-shaped structures connected by rotation, or it can be integrally formed. The upper surface of plate 1 has a walking area.

[0095] Please see Figure 7 and Figure 8 In some embodiments, the upper surface of the plate 1 also has a cleaning area 102.

[0096] It should be noted that the slots 2 located on the lower surface of the plate 1 can be distributed only in the area opposite to the walking area 101, or only on the side opposite to the cleaning area 102, or simultaneously in the area opposite to both the walking area 101 and the cleaning area 102.

[0097] Please see Figure 9 and Figure 10 The slot 2 located on the bottom surface of the plate 1 can be an inverted "F" shaped structure, or a similar U-shaped or C-shaped structure. The opening 21 of the slot 2 includes a guide limiting surface 211 and an abutting limiting surface 212. One end of any guide limiting surface 211 in the second direction Y points to the abutting limiting surface 212, and the other end points to the free end of the slot 2.

[0098] When the slot 2 contacts the mating structure on the base 20, the slot 2 can be fixed by the friction or interference fit between the guide limiting surface 211 and the base 20. Specifically, when the slot 2 is inserted relative to the base 20 along the second direction Y, the guide limiting surface 211 of the slot 2 can contact the surface of the mating structure on the base 20. At this time, a certain relative force, such as friction, will be generated between the two. As the slot 2 continues to move until the abutting limiting surface 212 abuts against the mating structure, the mating structure forms a physical blocking limit on the slot 2, indicating that the slot 2 has achieved mating with the base 20 and the ramp plate 10 is installed in place. When it is necessary to remove the ramp plate 10, only a force opposite to the insertion direction needs to be applied to separate the guide limiting surface 211 from the mating structure on the base 20.

[0099] Specifically, there are two guide limiting surfaces 211, which are arranged opposite each other along the first direction X.

[0100] Please see Figure 9 At least a portion of the surface of the aforementioned guide limiting surface 211 may be a plane parallel to the second direction Y, or it may be a plane or curved surface structure that is approximately parallel to or inclined at a certain angle to the second direction Y.

[0101] In some embodiments, all slots 2 may be configured to have the opening 21 structure described above, or at least some slots 2 may be configured to have the opening 21 structure described below.

[0102] At least one slot 2 also has an inclined guide surface 213, see [link to relevant documentation]. Figure 10 The guide surface 213 can be connected to the guide limiting surface 211 and the abutment limiting surface 212 to form a configuration as shown below. Figure 10 The structure of slot 2 is shown.

[0103] Specifically, one end of the guide surface 213 is connected to the guide limiting surface 211, and the other end is inclined away from the center of the slot 2. When the slot 2 is inserted into the cleaning device 100 along the second direction Y and comes into contact with the insertion and mating structure on the base 20, the inclined guide surface 213 can contact the insertion and mating structure through the inclined surface and generate a radial component force perpendicular to the second direction Y (i.e., a force in the first direction X). This component force can guide the insertion port of the slot 2 to quickly align with the insertion and mating structure in the first direction X, avoiding displacement interference in the first direction X and affecting the insertion efficiency of the ramp plate 10.

[0104] When the number of the aforementioned guide surfaces 213 is two and they are arranged opposite each other along the first direction X, please refer to... Figure 10 At this time, the opening 21 of the slot 2 has a flared structure. The flared structure can reduce the difficulty of the slot 2 and the base 20 to be inserted and mated, and guide the slot 2 and the base 20 to be quickly inserted and mated.

[0105] Of course, in other embodiments, the guide surface 213 may be located only on one side of the opening 21 in the first direction X.

[0106] The walking area 101, located on the upper surface of the ramp slab 10, is designed to cooperate with the corresponding ground cleaning unit 200 to guide the ground cleaning unit 200 smoothly into the cleaning equipment 100, thereby improving the climbing stability of the ground cleaning unit 200. Please refer to... Figure 11 The walking area 101 is an inclined slope structure, with the slope height near the end inside the cleaning equipment 100 being higher than the slope height at the end pointing outside the cleaning equipment 100.

[0107] Specifically, there are two ramps, spaced apart along the third direction Z on the upper surface of the plate 1, so that they can respectively cooperate with the two wheels of the ground cleaning host 200. The two ramps have the same shape, each including multiple spaced sub-ramps. The surface of the sub-ramp is a curved arc, and the curvature of the sub-ramp near the starting end is relatively gentle, so as to ensure that the ground cleaning host 200 can smoothly transition from the mounting surface to the top of the ramp plate 10 through the sub-ramp. The adjacent sub-ramps can be connected by a plane, and the transition at the connection is smooth, so as to ensure that the overall slope of the ramp plate 10 is relatively gentle. As the ground cleaning host 200 moves along the upper surface of the ramp plate 10 into the cleaning equipment 100, the sub-ramps and the connecting plane cooperate with each other to overcome gravity and move upward and gradually rise, achieving a stable increase in height, and finally successfully entering the cleaning equipment 100.

[0108] It should be noted that the above-mentioned slope has an anti-slip surface with a relatively complex stripe or other similar texture to help increase the friction between the ground cleaning host 200 and the ramp 10 during the climbing process and prevent the ground cleaning host 200 from slipping.

[0109] In this embodiment, the cleaning device 100 has a drum 30 for treating clothes. When the drum 30 operates and causes the cleaning device 100 to shake or vibrate, the ramp 10 mounted on the base 20 of the cleaning device 100 will also shake or vibrate relative to the base 20 due to the aforementioned action.

[0110] To prevent noise from the ramp 10 caused by the aforementioned vibrations and to improve the user experience, in some embodiments, the bottom surface of the ramp 10 is provided with several buffer members. When the ramp 10 is connected to the base 20, the buffer members are located between the ramp 1 and the base 20.

[0111] For example, the buffer can be a structure such as a rubber pad. Taking the cylinder 30 of the cleaning equipment 100 having a washing function as an example, the buffer can provide support and cushioning for the ramp 10 when the cylinder 30 is performing dehydration operations, so as to prevent the ramp 10 from vibrating and making noise relative to the base 20 due to the influence of the cylinder 30.

[0112] Specifically, the aforementioned buffer can be located on the bottom surface of the plate 1 (e.g., the first surface 1031) and can contact the base 20 when the ramp plate 10 is installed on the base 20. In this case, the buffer and the plug-in structure are arranged at intervals on the bottom surface of the plate 1. Of course, the buffer can also be located on the second surface 1032 of the plate 1 for contact with the mounting surface, reducing vibration noise that may be generated at the connection between the plate 1 and the mounting surface.

[0113] The number of buffer components can be one or more, and their specific shape and quantity can be flexibly adjusted according to actual needs.

[0114] It is understood that the ramp 10 provided in this application embodiment can be detachably connected to the base 20 of the cleaning equipment 100 through a plug-in structure, so that the ramp 10 can be easily installed and removed from the base 20, so that the user can remove the ramp 10 from the cleaning equipment 100 and clean the ramp 10 as needed, thereby improving the user experience.

[0115] Based on the same concept, this application also provides a cleaning device 100, including a base 20 and the ramp 10 described above. Of course, the cleaning device 100 also includes a cylinder 30 and a base station module 40.

[0116] The following is a detailed description of the disassembly and assembly structure of the ramp plate 10, the base plate 20, and the base station module 40.

[0117] Figure 12 This is a schematic diagram of the assembly of the ramp 10 and the base 20 provided in the embodiments of this application. Figure 13 for Figure 12 Enlarged view of the structure of region D in the middle. Figure 14 for Figure 12 Enlarged view of the structure of region E in the middle. Figure 15 This is a schematic diagram of the assembly of the ramp 10, base 20 and base station module 40 provided in the embodiments of this application.

[0118] Please see Figure 12 and Figure 13 The plug-in mating structure set on the base 20 as described above can be a plug-in through hole 201. The base 20 is plugged into the ramp plate 10 through the plug-in through hole 201 to achieve a detachable connection.

[0119] When installing the ramp 10, the slot 2 on the ramp 10 can be inserted into the side wall of the insertion hole 201 to achieve the installation and fixation of the ramp 10.

[0120] The base 20 includes a base plate having two regions with different upper surface heights in a first direction X: a first region 210 and a second region 220. The second region 220 is recessed relative to the first region 210, and a through hole 201 is provided in the second region 220. This arrangement helps to reduce the installation height of the ramp plate 10 fixed to the base 20, thereby reducing the height difference between the ramp plate 10 and the mounting surface.

[0121] In some embodiments, the base 20 further includes a flange integrally formed with the base plate. At one end of the base 20 facing the second direction Y, the flange mates with the base plate to form an opening 21. In this case, the flange can precisely avoid the second region 220 on one side in the second direction Y, allowing the second region 220 to connect to the outside of the base 20 through the opening 21. The ramp 10 can be inserted into the base 20 and connected to the base 20 through this opening 21.

[0122] Please see Figure 12 The opening 21 is opened on the front side of the base 20. One end of the second region 220 in the second direction Y is connected to the outer edge of the front part of the base 20. In the first direction X, part of the orthographic projection of the first region 210 is located outside the orthographic projection of the second region 220 in the second direction Y, and part of the orthographic projection is located on both sides of the orthographic projection of the second region 220 in the third direction Z. At this time, the first region 210 has a U-shaped or approximately C-shaped structure arranged around part of the periphery of the second region 220.

[0123] Please see Figure 13 The shape of the insertion hole 201 provided on the base 20 includes at least one of square and strip shapes.

[0124] When the slot 2 of the ramp 10 is inserted into the insertion hole 201 and inserted relative to the base 20 in the second direction Y, the slot 2 can contact the peripheral surface of the insertion hole 201 through the guide limiting surface 211 until the abutment limiting surface 212 of the slot 2 abuts against the side wall that surrounds the insertion hole 201. At this time, the insertion hole 201 forms a physical blocking limit on the slot 2, and the slot 2 is inserted into the insertion hole 201. At this time, the ramp 10 and the base 20 are assembled. For its structure, please refer to [link to relevant documentation]. Figure 13 When it is necessary to remove the ramp 10 from the base 20, simply apply a force opposite to the insertion direction to separate the guide limiting surface 211 from the surface of the base 20.

[0125] When the ramp 10 is installed on the base 20, please refer to Figure 14 The ramp 10 can contact the upper surface of the base 20 through the first surface 1031. At this time, part of the plate 1 is located outside the base 20 and can protrude downward relative to the base 20. The second surface 1032 is located below the first surface 1031.

[0126] With the base station module 40 and base 20 installed and engaged, the base station module 40 has a mounting port 401 on the side facing the second direction Y. The ramp 10 can be mounted on the base 20 through the mounting port 401 to connect with the base station module 40. Correspondingly, the ground cleaning host 200 can also enter and exit relative to the base station module 40 through the ramp 10 and mounting port 401.

[0127] To further improve the installation stability of the ramp plate 10 and prevent it from falling off the base 20 under external impact, the ramp plate 10 can be snapped into the base station module 40 to limit the displacement of the ramp plate 10 relative to the base station module 40, thereby improving the ease of installation and disassembly of the parallel ramp plate 10 and its reliability.

[0128] In some embodiments, one of the base station module 40 and the ramp 10 is provided with a trigger 410, and the other is provided with a limiting hole 104 that cooperates with the trigger 410. The base station module 40 and the ramp 10 are detachably connected through the trigger 410 and the limiting hole 104.

[0129] Please see Figure 15 In this embodiment, the ramp 10 is provided with a limiting hole 104 near the front side of the cleaning equipment, and the base station module 40 is provided with a trigger 410 that cooperates with the limiting hole 104.

[0130] Specifically, the trigger 410 is disposed on the base station module 40 and located at a position on or near the mounting port 401 of the base station module 40.

[0131] The aforementioned locking structure between the limiting hole 104 and the trigger 410 is a reversible locking structure, such as a snap-fit ​​structure. Taking the snap-fit ​​connection between the trigger 410 and the limiting hole 104 as an example, when the two are snap-fitted together, the ramp 10 can be locked relative to the base station module 40; when the user needs to remove the ramp 10, the ramp 10 can be unlocked by actively operating the trigger 410.

[0132] Specifically, the trigger 410 is configured to separate from the limit hole 104 when triggered.

[0133] For example, the trigger condition of the trigger 410 can be set to pressing, and the trigger 410 can be set to include a pressing part and an elastic part. The pressing part can extend out under the push of the elastic part and pass through the limiting hole 104. When the pressing part is pressed by an external force, it can squeeze and compress the elastic part, and the pressing part in the pressing state can be separated from the limiting hole 104.

[0134] In this embodiment, there are two trigger elements 410, which are located on both sides of the mounting port 401 in the third direction Z. Correspondingly, there are also two limiting holes 104 on the ramp plate 10, which are set one-to-one with the trigger elements 410. The two limiting holes 104 are arranged opposite to each other in the third direction Z.

[0135] Of course, in other embodiments, the limiting hole 104 can be adjusted to be opened on the base station module 40, and the trigger 410 can be opened on the ramp plate 10.

[0136] Based on the same concept, this application also provides a cleaning system 1000, please refer to... Figure 1 The cleaning system 1000 includes the aforementioned cleaning equipment 100, and also includes a floor cleaning unit 200. The floor cleaning unit 200 can enter and exit relative to the cleaning equipment 100 via the ramp 10 to cooperate with the cleaning equipment 100. Of course, the floor cleaning unit 200 can also be parked inside the cleaning equipment 100 via the ramp 10.

[0137] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0138] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
