Description

Technical Field

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

[0002] In related technologies, cleaning robots are used to clean floors. The cleaning robots are equipped with base stations, which can provide cleaning functions for the cleaning robots. For example, after the cleaning robot's cleaning parts, such as a rag, finish cleaning the floor, the cleaning robot returns to the base station and washes the rag in the base station's cleaning tank. After the rag is washed, the wastewater in the cleaning tank is pumped away, while solid waste remains in the cleaning tank. Each time the rag is washed, the user needs to manually clean the cleaning tank. Otherwise, the waste in the cleaning tank may re-adhere to the rag and contaminate it, resulting in a poor user experience. Summary of the Invention

Detailed Implementation

[0046] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0047] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] One embodiment of this application provides a base station, base station 100 for cleaning robots.

[0049] Please see Figure 1 , Figure 2 and Figure 3 The base station 100 includes a housing 1, a filter 2, and a cleaning bracket 3. A cleaning tank 1a is formed within the housing 1. The filter 2 is disposed within the cleaning tank 1a and has a storage tank 21 and a dust port 22, the dust port 22 connecting the storage tank 21 and the cleaning tank 1a. The cleaning bracket 3 is movably disposed within the cleaning tank 1a. A cleaning surface 3a is formed on the upper surface of the cleaning bracket 3, and a sweeping surface 3b is formed on the lower surface of the cleaning bracket 3. The cleaning surface 3a is used to contact the cleaning components of a cleaning robot, and the sweeping surface 3b is in contact with the bottom surface of the cleaning tank 1a. The cleaning bracket 3 moves to drive the material in the cleaning tank 1a through the dust port 22 into the storage tank 21.

[0050] It is understood that the substances mentioned here include, but are not limited to, solid waste, such as large particles of waste such as fruit peels, nutshells, cigarette butts, and / or paper scraps.

[0051] In this embodiment, by movably setting the cleaning bracket 3 inside the cleaning tank 1a, on the one hand, the cleaning surface 3a can clean the cleaning parts of the cleaning robot to ensure their cleanliness. This provides the cleaning robot with clean cleaning parts for the next cleaning of the floor, avoiding secondary pollution to the floor caused by unclean cleaning parts. On the other hand, the sweeping surface 3b can sweep the material that falls into the cleaning tank 1a into the storage tank 21 through the dust inlet 22. This achieves the cleaning of solid waste, preventing it from being exposed in the cleaning tank 1a and causing odors. In this way, the user does not have to clean the cleaning tank 1a every time the cleaning bracket 3 cleans the cleaning parts, and it also avoids secondary pollution of the cleaning parts by the solid waste remaining in the cleaning tank 1a. This makes it easier for the user to clean and provides a better user experience.

[0052] Another embodiment of this application provides a cleaning system, including a base station 100 as described in any embodiment of this application and a cleaning robot. The cleaning robot includes a main unit and a cleaning component rotatably disposed at the bottom of the main unit.

[0053] In this embodiment, the cleaning system allows the cleaning bracket 3 to be movably installed within the cleaning tank 1a. On one hand, the cleaning surface 3a can be used to clean the cleaning parts of the cleaning robot, ensuring their cleanliness. This provides the cleaning robot with clean cleaning tools for the next cleaning, preventing secondary pollution to the floor caused by unclean cleaning parts. On the other hand, the cleaning surface 3b can sweep any material that falls into the cleaning tank 1a into the storage tank 21 through the dust inlet 22. This allows for the removal of large particles of debris, preventing them from being exposed on the cleaning tank 1a and causing odors. Storing the material temporarily in the storage tank 21 also facilitates unified cleaning by the user, resulting in a better user experience.

[0054] A cleaning robot can include a control unit and a walking mechanism. The control unit can control the walking mechanism to move autonomously and the cleaning components to perform autonomous operations. Taking rollers as an example of the walking mechanism, the control unit controls the rollers to roll, thereby driving the cleaning robot to move. During the robot's movement, the cleaning components can clean the ground.

[0055] The appearance or shape of the cleaning robot is not limited; for example, a cleaning robot can be roughly flat and disc-shaped.

[0056] Cleaning components are used to clean surfaces such as floors and tabletops. These components can roll, rotate, or slide relative to the surface, causing them to rub against the surface and thus achieving the cleaning purpose.

[0057] For example, cleaning components include, but are not limited to, roller brushes and / or cloths, etc.

[0058] The appearance and shape of the cleaning component are not limited; for example, the cleaning component may be generally circular.

[0059] In one embodiment, a plane perpendicular to the vertical direction is used as the projection plane, and the projected area of ​​the cleaning tank 1a is greater than or equal to the total projected area of ​​the cleaning component. For example, the shape of the cleaning tank 1a is not limited; for instance, the cleaning tank 1a can be formed by joining two circular grooves, each with a diameter 10mm to 30mm larger than the diameter of the cleaning component. This allows for thorough cleaning of the entire cleaning component, preventing waste and wastewater from flowing out of and falling into the cleaning tank 1a after cleaning, resulting in a better user experience.

[0060] In one embodiment, the cleaning bracket 3 is rotatably disposed within the cleaning tank 1a. This facilitates full contact between the cleaning bracket 3 and the cleaning components, enabling more efficient cleaning of both the cleaning components and the bottom surface of the cleaning tank 1a, resulting in high efficiency.

[0061] In one exemplary embodiment, a drive device, such as a motor, drives the cleaning bracket 3 to rotate. This provides high controllability.

[0062] In one embodiment, the cleaning component drives the cleaning bracket 3 to rotate. This utilizes the rotation of the cleaning component to drive the rotation of the cleaning bracket 3, reducing the additional driving cost of the drive unit and improving economic efficiency.

[0063] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The housing 1 includes a limiting platform 11 disposed within the cleaning tank 1a, and the cleaning bracket 3 is capable of avoiding or abutting against the limiting platform 11 in its rotational direction. For example, the circumferential surface of the limiting platform 11 has a limiting surface protruding into the cleaning tank 1a, which the cleaning bracket 3 abuts against during rotation to restrict its rotation. Thus, when the cleaning bracket 3 rotates clockwise and counterclockwise, it abuts against the limiting platform 11, preventing it from continuing to rotate in its previous direction.

[0064] When the cleaning bracket 3 is abutting against the limiting platform 11, the cleaning bracket 3 can rotate relative to the cleaning component. When the cleaning bracket 3 is avoiding the limiting platform 11, the cleaning bracket 3 can rotate relative to the bottom surface of the cleaning tank 1a. In other words, when the cleaning bracket 3 is abutting against the limiting platform 11, the cleaning bracket 3 remains relatively stationary with respect to the housing 1, and the cleaning component can rotate relative to the cleaning bracket 3. This allows the cleaning surface 3a to scrub the cleaning component, thereby cleaning away debris. When the cleaning bracket 3 is avoiding the limiting platform 11, the cleaning bracket 3 is in an active state and can rotate relative to the bottom surface of the cleaning tank 1a. This allows the cleaning surface 3b to scrub the bottom surface of the cleaning tank 1a, thereby sweeping debris from the bottom surface of the cleaning tank 1a into the storage tank 21.

[0065] For example, in one specific embodiment, please refer to Figure 1The limiting platform 11 has a forward rotation limiting surface 11a and a reverse rotation limiting surface 11b. When the cleaning bracket 3 rotates forward and abuts against the forward rotation limiting surface 11a, the cleaning bracket 3 will be unable to continue rotating forward. Similarly, when the cleaning bracket 3 rotates backward and abuts against the reverse rotation limiting surface 11b, the cleaning bracket 3 will be unable to continue rotating backward. Taking forward rotation as an example, when the cleaning component drives the cleaning bracket 3 to rotate forward together, before the cleaning bracket 3 abuts against the forward rotation limiting surface 11a, the cleaning component and the cleaning bracket 3 rotate synchronously. At this time, the cleaning surface 3b of the cleaning bracket 3 can clean the bottom surface of the cleaning tank 1a, sweeping the material in the cleaning tank 1a into the storage tank 21 through the dust inlet 22, avoiding the material being exposed on the cleaning tank 1a, making cleaning easier and providing a better user experience. After the cleaning bracket 3 abuts against the forward rotation limiting surface 11a, the cleaning bracket 3 will be unable to continue rotating forward and will remain at the forward rotation limiting surface 11a. Since the cleaning component and the cleaning bracket 3 only rotate forward, the cleaning component and the cleaning bracket 3 rotate synchronously. The contact rotation occurs when the cleaning bracket 3 stops rotating, while the cleaning component continues to rotate forward. This creates a relative rotation between the two components, allowing the cleaning surface 3a on the cleaning bracket 3 to clean the cleaning component above it, scraping large and small particles of debris and wastewater into the cleaning tank 1a. When the cleaning component rotates in reverse, the cleaning bracket 3 moves away from the forward rotation limit surface 11a and begins to rotate in reverse along with the cleaning component. This cleans up any large particles of debris that fall into the cleaning tank 1a. The cleaning component then repeats the forward and reverse rotation actions described above to complete the repeated cleaning of the cleaning component and the processing of large particles of debris.

[0066] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The upper surface of the limiting platform 11 is formed with a water filling tank 11c, and the base station 100 includes a water filling nozzle 4 for filling water into the water filling tank 11c. Exemplarily, the water filling nozzle 4 includes a water spray hole 4a and two fixing screw holes 4b. The water spray hole 4a is located in the middle of the two fixing screw holes 4b. The two fixing screw holes 4b are fixed to the side wall of the cleaning tank 1a by fasteners such as screws or bolts. The water spray hole 4a is located above the water filling tank 11c. In this way, by adding water downward into the water filling tank 11c, clean water is provided for subsequent cleaning of the cleaning components.

[0067] As an example, in one embodiment, please refer to Figure 2 and Figure 5 The base station 100 is also equipped with a clean water tank 8, and the water inlet 4 also includes a connection hole 4c. The clean water tank 8 is connected to the connection hole 4c through a pipe, which can provide a continuous source of clean water to the water tank 11c.

[0068] In one embodiment, please refer to Figure 1 and Figure 6The cleaning surface 3a has a flow channel 3a1. When the cleaning bracket 3 is in contact with the limiting platform 11, the water tank 11c is connected to the flow channel 3a1. For example, when the cleaning bracket 3 is in the contacting state, such as when the cleaning bracket 3 is in contact with the forward limiting surface 11a and / or the reverse limiting surface 11b, the tail end of the water tank 11c is connected to the head end of the flow channel 3a1, so that clean water can flow into the flow channel 3a1 through the water tank 11c to wet and clean the cleaning parts; when the cleaning bracket 3 is in the avoidance state, clean water can flow into the cleaning tank 1a through the water tank 11c to wet some light and small debris such as dust or paper, so as to facilitate the subsequent cleaning of the cleaning surface 3b.

[0069] In one embodiment, please refer to Figure 1 , Figure 7 and Figure 8 The filter 2 has a sewage channel 2a and a filter hole 2b that connects to the cleaning tank 1a and the sewage channel 2a. In this way, sewage and small particles of garbage mixed in with the sewage can be collected together through the filter hole 2b into the sewage channel 2a for subsequent unified treatment, while large particles of garbage are temporarily stored in the storage tank 21 to avoid clogging the sewage channel 2a.

[0070] In one embodiment, please refer to Figure 1 and Figure 9 The base station 100 includes a sewage nozzle 5, which includes an outlet 5a and a negative pressure suction port 5b connected to the outlet 5a. The negative pressure suction port 5b is connected to a sewage channel 2a. In this way, sewage and small particulate debris in the sewage channel 2a can be sucked up through the sewage nozzle 5. For example, the base station 100 includes a water pump connected to the negative pressure suction port 5b to pump sewage from the sewage channel 2a.

[0071] As an example, in one embodiment, please refer to Figure 2 and Figure 9 The base station 100 is also equipped with a sewage tank 9, which is connected to the water outlet 5a via a pipe. In this way, the sewage and small particulate waste sucked up by the sewage nozzle 5 will be temporarily stored in the sewage tank 9 through the pipe, avoiding contact with the air and affecting air quality. This provides a better user experience and also facilitates the unified treatment of sewage by users.

[0072] In one embodiment, please refer to Figure 1 , Figure 7 and Figure 8There are multiple storage tanks 21, which are distributed along the length of the cleaning tank 1a on both sides of the sewage channel 2a. For example, the number of storage tanks 21 is not limited. For instance, there can be two storage tanks 21, which can be distributed along the length of the cleaning tank 1a on both sides of the sewage channel 2a to ensure that the material on both sides can be swept from the dust inlet 22 into the storage tank 21, avoiding exposure to the cleaning tank 1a and generating odors, thus improving the user experience.

[0073] In one embodiment, please refer to Figure 7 The storage tank 21 has a drain outlet 21a on its wall, which connects the sewage channel 2a to the storage tank 21. This allows the sewage remaining in the storage tank 21 to flow into the sewage channel 2a through the drain outlet, preventing substances from being soaked in sewage for a long time and causing odors. Also, it makes it inconvenient to pour out the substances when there is sewage in the storage tank 21.

[0074] The maximum width of the drain outlet 21a is smaller than the maximum width of the filter hole 2b. In this way, the material can only enter the storage tank 21 from the dust inlet 22, and the material will not enter the sewage channel 2a from the drain outlet 21a, causing the sewage nozzle 5 to become clogged. The waste sorting and treatment is clear and efficient.

[0075] For example, in one embodiment, the shape of the dust inlet 22 is not limited. For example, the shape of the dust inlet 22 can be a square, rectangle, circle or other irregular shape, and the size of the dust inlet 22 is determined by the ability to hold the substance.

[0076] For example, in one embodiment, the shape of the filter hole 2b is not limited. For example, the shape of the filter hole 2b can be a square, a rectangle, a square circle, or other irregular shapes. The size of the filter hole 2b can be determined according to the size of the small particles of waste to achieve the effect of limiting filtration and avoid clogging the sewage nozzle 5.

[0077] In one embodiment, please refer to Figure 1 , Figure 4 , Figure 7 and Figure 8 The filter 2 is detachably connected to the housing 1. For example, the bottom of the cleaning tank 1a is recessed to form a mounting groove 1a1 that matches the shape of the filter 2. A snap fastener 2c is formed at the end of the filter 2 away from the limiting platform 11, and a protruding post (not shown) is formed on the side of the mounting groove 1a1 away from the limiting platform 11. The snap fastener 2c engages with the protruding post to install the filter 2 in the mounting groove 1a1. Thus, after the material is swept into the storage tank 21, the user can manually disassemble the filter 2 for cleaning, making installation and disassembly convenient. In some embodiments, the depth of the mounting groove 1a1 is equal to the thickness of the filter 2, thus not restricting the rotation of the cleaning bracket 3, resulting in a compact structure.

[0078] In one embodiment, please refer to Figure 8 The filter 2 includes an upper cover 23 and a lower plate 24. The upper cover 23 has a dust inlet 22 and a water filter hole 2b. The lower plate 24 is disposed below the upper cover 23 to jointly define a storage tank 21 and a sewage channel 2a. The upper cover 23 and the lower plate 24 are detachably connected. For example, one of the upper cover 23 and the lower plate 24 has a protrusion 241, and the other has a slot 231. The protrusion 241 engages with the slot 231. For example, five protrusions 241 are formed on the lower plate 24, and the five protrusions 241 are distributed at the edge of the lower plate 24. The upper cover 23 has a slot 231 formed on the side surface near the lower plate 24. The number of slots 231 can be five, and the five slots 231 are distributed at positions corresponding to the protrusions 241. In this way, after the user removes the filter 2, if the material cannot be poured out from the dust port 22 or if the storage tank 21 and sewage channel 2a need to be cleaned, the user can manually open the filter 2 to facilitate cleaning of its interior, which is highly efficient.

[0079] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 8 The base station 100 includes a liquid level detection device 6 installed on the filter 2, which is used to detect the water level in the cleaning tank 1a. For example, the liquid level detection device 6 can be a float assembly 6a. For instance, the float assembly 6a includes a float upper cover 6a1, a magnet 6a2, and a float lower cover 6a3. The float lower cover 6a3 is installed inside the float upper cover 6a1 via the magnet 6a2. A receiving cavity 2d is formed on the side of the filter 2 away from the snap fastener 2c. A pivot hole 2d1 is provided on the inner wall of the receiving cavity 2d. Two elastic arms 6a11 are formed on one side of the float upper cover 6a1. Rotating protrusions 6a12 extending toward the pivot hole 2d1 are formed on the elastic arms 6a11. When installing the float accessory, the two elastic arms 6a11 can be pinched by hand to cause elastic deformation, so that the rotating protrusions 6a12 can be locked in the pivot hole 2d1. In this way, when detecting the liquid level, one side of the float assembly 6a is used to detect the liquid level, and the other side can rotate with the rise and fall of the liquid level to detect the liquid level of the cleaning tank 1a in real time.

[0080] Understandably, when the liquid level reaches the preset level, the wastewater nozzle 5 can be activated to clean the wastewater and lower the liquid level in the cleaning tank 1a. If the liquid level does not drop significantly after activating the wastewater nozzle 5, the various channels of the wastewater nozzle 5 and the filter 2 can be checked to determine if any blockage has occurred.

[0081] In one embodiment, please refer to Figure 1 and Figure 2There are two cleaning brackets 3, and the filter 2 is located between the two cleaning brackets 3. For example, the two cleaning brackets 3 are distributed on both sides of the filter 2 along the length of the cleaning tank 1a. In this way, the two cleaning parts on the cleaning robot can be cleaned at the same time. The sewage and small particles of debris after the cleaning parts are cleaned can enter the sewage channel 2a through the middle through the water filter hole 2b. The material that falls from the two cleaning parts can be swept into the storage tank 21 from the dust inlet 22 on each side through the cleaning brackets 3 on both sides. The cleaning efficiency is high.

[0082] In one embodiment, please refer to Figure 4 , Figure 6 and Figure 10 The cleaning bracket 3 includes a fixing base 31, a bracket body 32, and a bracket arm 33. The fixing base 31 is fixedly disposed on the bottom surface of the cleaning tank 1a. For example, a first mounting hole 31a is formed on the fixing base 31, and a second mounting hole 1a2 is formed on the bottom surface of the cleaning tank 1a. Fasteners such as screws or studs can pass through the first mounting hole 31a and the second mounting hole 1a2 to fix the fixing base 31 to the bottom surface of the cleaning tank 1a to provide stable support.

[0083] The support body 32 is rotatably connected to the fixed base 31. The support arm 33 is disposed on the circumferential surface of the support body 32, with a cleaning surface 3a formed on the upper surface and a sweeping surface 3b formed on the lower surface. Thus, by rotating the support arm 33 on the support body 32, the cleaning components and substances on the cleaning tank 1a can be cleaned thoroughly, preventing substances from being exposed on the cleaning tank 1a and improving the user experience.

[0084] In one embodiment, the dust inlet 22 is within the travel trajectory formed during the rotation of the support arm 33. Thus, during the rotation of the support arm 33, material on the cleaning tank 1a can be swept through the dust inlet 22 into the storage tank 21, facilitating cleaning and material storage.

[0085] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The number of support arms 33 is multiple, and the multiple support arms 33 are arranged at intervals along the axial direction of the support body 32. For example, the shape of the support body 32 is not limited, such as cylindrical, conical, frustum-shaped, spherical, or other shapes. The number of support arms 33 is not limited, for example, there can be 2, 3, 4 or more. Taking 3 support arms 33 as an example, the 3 support arms 33 are arranged on the support body 32 at circumferential intervals of 120°. In this way, the cleaning tank 1a can be repeatedly cleaned at the same rotation speed to ensure that the material in the cleaning tank 1a can be swept from the dust inlet 22 to the storage tank 21 with less material residue and high cleanliness.

[0086] In one embodiment, please refer to Figure 3 , Figure 6 and Figure 10 The support body 32 includes a bottom cover 321 and a connecting body 322. The bottom cover 321 is rotatably fitted onto the fixed seat 31. Exemplarily, a through hole is formed in the middle of the bottom cover 321, extending vertically. An annular retaining ring is formed on the side of the fixed seat 31 away from the bottom surface of the cleaning tank 1a. The diameter of the annular retaining ring is larger than the diameter of the through hole. During installation, the fixed seat 31 can be first fitted onto the through hole and then fixed to the bottom surface of the cleaning tank 1a. This prevents the bottom cover 321 from detaching from the fixed seat 31 during rotation, resulting in a compact structure and good operational stability. In some embodiments, the bottom cover 321 and the fixed seat 31 are clearance-fitted, ensuring that the bottom cover 321 can rotate relative to the fixed seat 31.

[0087] The support arm 33 is disposed on the circumferential surface of the connection. One of the bottom cover 321 and the connecting body 322 forms a limiting block 3211, and the other of the bottom cover 321 and the connecting body 322 forms a limiting groove 3221. For example, three outwardly extending limiting blocks 3211 are formed on the outer periphery of the bottom cover 321 near the connecting body 322. The three limiting blocks 3211 are arranged at 120° intervals in the circumferential direction. The circumferential sidewall of the connecting body 322 forms three limiting grooves 3221. The three limiting grooves 3221 are arranged at 120° intervals in the circumferential direction. The limiting blocks 3211 and the limiting grooves 3221 engage with each other to limit the relative rotation between the connecting body 322 and the chassis, resulting in a compact structure.

[0088] In one embodiment, the support body 32 is a flexible structure. For example, the support body 32 can be made of a flexible material such as silicone or rubber. See also... Figure 3 , Figure 6 and Figure 10 An annular baffle strip 3212 is formed on the lower surface of the support body 32. The baffle strip 3212 surrounds the outer periphery of the fixing seat 31 and abuts against the bottom surface of the cleaning tank 1a. For example, an annular baffle strip 3212 is formed on the side of the bottom cover 321 away from the limiting block 3211. In this way, during the rotation of the cleaning support 3, the baffle strip 3212 always remains in contact with the bottom surface of the cleaning tank 1a. On the one hand, it can prevent substances from entering the center of rotation and causing jamming; on the other hand, it can protect the bottom cover 321 and the fixing seat 31 to a certain extent, improving service life and working stability.

[0089] In one embodiment, please refer to Figure 3The lower surface of the support arm 33 is provided with a flexible scraper strip 331, the lower surface of which is the cleaning surface 3b. The flexible scraper strip 331 can be made of a soft material such as silicone or rubber. In this way, on the one hand, the cleaning ability of the cleaning tank 1a can be further improved, making the cleaning more thorough; on the other hand, the use of the flexible scraper strip 331 can also reduce damage to the bottom surface of the cleaning tank 1a, thereby increasing the service life of the cleaning tank 1a.

[0090] Flexible materials are materials that can be deformed by compression.

[0091] In one embodiment, for example, the shape of the flexible scraping strip 331 is not limited; for example, it can be a long strip.

[0092] For example, in one embodiment, the flexible scraper strip 331 is connected to the support arm 33 by forming a limiting groove with a gradually changing groove width on the lower surface of the support arm 33. This allows the flexible scraper strip 331 to be inserted into the limiting groove from the side with the larger groove width, thus completing the installation of the flexible scraper strip 331. When it needs to be removed and replaced, it can simply be pulled out from the side with the larger groove width, making installation and removal convenient. In some embodiments, the connection between the flexible scraper strip 331 and the support arm 33 can also be achieved by screwing, etc.

[0093] In one embodiment, please refer to Figure 1 and Figure 6 The cleaning surface 3a has protruding ribs 3a2. For example, the shape of the protruding ribs 3a2 is not limited. For example, the shape of the protruding ribs 3a2 can be frustum, cylinder, or strip, etc. Of course, a combination of various shapes can also be used, such as both strip-shaped and frustum-shaped protruding ribs 3a2. The specific shape depends on the type of substance. That is to say, special protruding ribs 3a2 can be set for special types of substances to achieve the purpose of cleaning.

[0094] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 6 The cleaning bracket 3 includes a cleaning brush 34, which is located at the end of the bracket arm 33 away from the bracket body 32. The cleaning brush 34 contacts the side wall of the cleaning tank 1a. For example, the cleaning brush 34 can be a tuft of straight bristles. This allows for thorough cleaning of the side walls and corners of the cleaning tank 1a, providing good cleaning ability. It is understood that due to centrifugal force during rotation, some of the material on the cleaning tank 1a will be thrown onto the side wall of the cleaning tank 1a. Therefore, the flexible scraper strip 331 alone cannot clean these edges and corners.

[0095] In one embodiment, please refer to Figure 1 , Figure 7 and Figure 8 The dust inlet 22 has scraping ribs 22a on its peripheral sidewall, which extend from the peripheral sidewall towards the central area of ​​the dust inlet 22. This allows the scraping ribs 22a to scrape away material such as lint and debris from the flexible scraper strip 331 into the storage tank 21 when cleaning the cleaning surface 3b, keeping the flexible scraper strip 331 clean and preventing secondary contamination caused by material carried on the flexible scraper strip 331 in the cleaning tank 1a.

[0096] In one embodiment, please refer to Figure 2 and Figure 4 The housing 1 includes a cleaning tray 12 and an upper housing 13. The cleaning tray 12 includes a tray body 121 and a ramp plate 122. A cleaning groove 1a is formed on the upper surface of the tray body 121. One end of the ramp plate 122 is connected to the tray body 121, and the other end of the ramp plate 122 is used to abut against the receiving cleaning surface. In this way, the cleaning robot can enter the cleaning groove 1a on the tray body 121 from the ramp plate to complete the cleaning of the cleaning parts, with a high degree of automation.

[0097] The upper shell 13 covers the disk body 121 to form a cleaning chamber 13a, the cleaning tank 1a is located inside the cleaning chamber 13a, and the ramp 122 is located outside the cleaning chamber 13a. In this way, the cleaning chamber 13a can protect the cleaning robot to a certain extent, while also reducing the floor space occupied by the cleaning robot, resulting in high space utilization.

[0098] In one embodiment, please refer to Figure 2 The inner wall of the cleaning chamber 13a is provided with a rotatable guide wheel 13a1, which is used to guide the main unit to a preset area in the cleaning chamber 13a. In this way, on the one hand, it can avoid damage caused by direct contact between the main unit and the inner wall of the cleaning chamber 13a, thus improving its service life; on the other hand, it can guide the main unit to a preset area, such as guiding the main unit into the cleaning tank 1a so that the cleaning parts come into contact with the cleaning surface 3a, resulting in a high degree of automation.

[0099] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The upper surface of the ramp 122 forms a guide 1221, which guides the main unit to a preset area in the cleaning chamber 13a. Here, when the cleaning robot climbs the ramp 122, the guide 1221 on the ramp 122 is positioned between the two cleaning components on the main unit. In this way, the main unit can enter the preset area along the guiding direction of the guide 1221 so that the cleaning components contact the cleaning surface 3a, resulting in a high degree of automation.

[0100] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The upper surface of the ramp plate is provided with anti-slip ribs 1222. For example, the shape of the anti-slip ribs 1222 can be a long strip with a certain curvature, a raised dot shape, or a combination of multiple shapes. For example, the guide member 1221 has anti-slip ribs 1222 on both sides along the length of the cleaning tank 1a. One side can be a long strip anti-slip rib 1222, and the other side can be a raised dot anti-slip rib 1222. In this way, the cleaning robot can smoothly reach the preset area and avoid the cleaning robot from sliding sideways on the ramp plate 122.

[0101] In one embodiment, the cleaning robot includes a first communication module, and the base station 100 includes a second communication module. The cleaning robot and the base station 100 can communicate via the first and second communication modules. For example, wireless communication can be performed via the first and second communication modules, and the cleaning robot can return to the cleaning tank 1a on its own.

[0102] For example, the first communication module and the second communication module may be one or more of the following wireless data communication modules, including but not limited to Bluetooth module, Wireless Fidelity (WIFI) module, fourth generation or fifth generation (4G / 5G) communication module or infrared module.

[0103] Base station 100 can also be used to provide functions such as charging and / or drying for cleaning robots.

[0104] In one embodiment, please refer to Figure 2 The base station 100 includes a fan and a drying duct 7 mounted on the housing 1. The drying duct 7 connects the fan and a cleaning tank 1a. The fan ventilates the cleaning tank 1a through the drying duct 7 to quickly dry the cleaned parts.

[0105] In one embodiment, the base station 100 includes a charging terminal and a power module electrically connected to the charging terminal. When the cleaning robot is located in the cleaning tank 1a, the cleaning robot can be electrically connected to the charging terminal to achieve charging. The power module is used to convert AC power from the mains to DC power, and the charging terminal uses DC power to charge the cleaning robot.

[0106] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
