Description

Clean base stations and cleaning systems Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning base station and a cleaning system. Background Technology

[0002] With the development of smart home technology, cleaning robots have become widely popular due to their high degree of automation and ease of use. To further enhance the user experience, cleaning base stations, as an important supporting facility for cleaning robots, not only provide charging functions but also clean the mop pads, ensuring that the mop remains clean after each use.

[0003] Existing cleaning base stations use a translating scraper arm to clean the mop tray. The translating scraper arm usually relies on linear drive mechanisms such as gears and racks. However, the space in the cleaning base station is limited, and the length of the rack laid in a straight line is also limited. Therefore, the range of motion of the scraper arm is also relatively limited, which means that the scraper arm cannot clean the corners and edges of the mop tray, resulting in poor cleaning ability of the cleaning base station for the mop tray. Summary of the Invention

[0004] This utility model discloses a cleaning base station and a cleaning system to solve the problem that the cleaning base station in the related technology has poor cleaning ability for the mop tray.

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows:

[0006] In a first aspect, this application discloses a cleaning base station, which includes a base, a scraper arm, and a drive mechanism, wherein:

[0007] The driving mechanism includes a driving component, a transmission component, and a synchronous wheel. The synchronous wheel is rotatably mounted on the base. One end of the scraper arm is fixedly connected to the synchronous wheel. The driving component is mounted on the base and connected to the transmission component, and is used to drive the synchronous wheel to rotate the scraper arm through the transmission component.

[0008] Secondly, this application also discloses a cleaning system, which includes a cleaning robot and the cleaning base station described in the first aspect, wherein the cleaning base station cooperates with the cleaning robot.

[0009] The technical solution adopted in this utility model can achieve the following technical effects:

[0010] The cleaning base station disclosed in this application discloses a drive mechanism comprising a drive component, a transmission component, and a synchronous wheel. The synchronous wheel is rotatably mounted on the base, and one end of the scraper arm is fixedly connected to the synchronous wheel. This allows the drive component to drive the synchronous wheel, which in turn drives the scraper arm to rotate, via the transmission component. The scraper arm then scrapes away wastewater from the mop tray through interference with the mop tray. Because the cleaning base station disclosed in this application uses a drive component to drive the synchronous wheel via the transmission component, which in turn drives the scraper arm to rotate and scrape the mop tray, the range of motion of the scraper arm is no longer limited by the length of the rack. This allows the scraper arm to cover a larger area of ​​the mop tray in a relatively small space, thereby improving the cleaning ability of the cleaning base station to clean the corners and edges of the mop tray.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Example 1:

[0040] Please refer to Figures 1 to 16. This application discloses a cleaning base station B, which is used to cooperate with a cleaning robot A. Specifically, the cleaning base station B has a robot docking space for the cleaning robot A to dock. When the cleaning robot A is docked in the robot docking space, the cleaning base station B can at least charge the cleaning robot A and clean the mop tray A1 of the cleaning robot A.

[0041] The cleaning base station B includes a base 100 and a scraper arm 200. Of course, in some embodiments, the cleaning base station B may also include a base station housing, the base station housing and the base 100 can form a robot docking space, and an entrance and exit communicating with the robot docking space, through which the cleaning robot A can enter and exit the robot docking space.

[0042] The base 100 can be the mounting base for at least some of the components of the cleaning base station B, and can also be used to collect the wastewater scraped off the mop disc A1 by the scraper arm 200 (the wastewater referred to here is a broad category, including foreign objects in the water, such as hair, sunflower seed shells, etc.).

[0043] The base 100 has a mop tray cleaning area. When the cleaning robot A is docked at the cleaning base station B, the mop tray A1 of the cleaning robot A is located in the mop tray cleaning area, which is part of the robot docking space.

[0044] One end of the scraper arm 200 is rotatably mounted on the base 100, and the other end extends into the mop tray cleaning area, allowing it to rotate within a preset angle range within the cleaning area. This preset angle range can be set based on the size and position of the mop tray A1, as well as the number of scraper arms 200 in the actual application. For example, taking one scraper arm 200 as an example, the angle at which the scraper arm 200 rotates to one extreme position within the mop tray cleaning area is recorded as 0°, and the angle at which the scraper arm 200 rotates to the other extreme position within the mop tray cleaning area is recorded as the maximum value of the preset angle range, such as 120°. Therefore, the preset angle range can be from 0° to 120°. Of course, the preset angle range can also be other ranges, specifically set according to the size and position of the mop tray A1 and the number of scraper arms 200 in the actual application. This embodiment does not impose specific limitations on the preset angle range.

[0045] Specifically, the first end of the scraper arm 200 is rotatably mounted on the base 100, and the second end of the scraper arm 200 extends into the cleaning area of ​​the mop tray. When the cleaning robot A is docked at the cleaning base station B, the scraper arm 200 is located below the mop tray A1 and interferes with the mop tray A1. Specifically, the scraper arm 200 can contact the bottom surface of the mop on the mop tray A1 (i.e., the generally downward-facing surface of the mop), thereby achieving interference.

[0046] When cleaning robot A is docked at cleaning base station B, the mop tray A1 of cleaning robot A is located in the mop tray cleaning area, and the scraper arm 200 rotates to scrape the mop tray A1, thereby scraping the mop on the mop tray A1.

[0047] Specifically, when the cleaning robot A is docked at the cleaning base station B, the scraper arm 200 interferes with the mop disc A1. During the rotation of the scraper arm 200, the scraper arm 200 scrapes the sewage off the mop disc A1 through the interference with the mop disc A1.

[0048] It should be noted that in the relevant technology, the scraper arm scrapes the mop disc in a translational manner. The translational scraper arm usually relies on linear drive mechanisms such as gears and racks. However, the space of the cleaning base station is limited, and the length of the rack laid in a straight line is limited. Therefore, the range of motion of the scraper arm is also relatively limited, which will result in the scraper arm being unable to clean the corners and edges of the mop disc.

[0049] The cleaning base station B disclosed in this application discloses a scraper arm 200 with one end rotatably mounted on the base 100 and the other end extending into the mop tray cleaning area. The scraper arm 200 can rotate within a preset angle range within the mop tray cleaning area. When the cleaning robot A is docked at the cleaning base station B, interference occurs between the scraper arm 200 and the mop tray A1. During rotation, the scraper arm 200 scrapes away wastewater from the mop tray A1 through this interference. Because the cleaning base station B disclosed in this application uses the rotation of the scraper arm 200 to scrape the mop tray A1, the range of motion of the scraper arm 200 is no longer limited by the length of the rack. This allows the scraper arm 200 to cover a larger area of ​​the mop tray A1 in a relatively small space, thereby improving the cleaning ability of the cleaning base station B to clean the corners and edges of the mop tray A1.

[0050] It should be noted that when the scraper arm in the related technology moves in a translational manner, all parts of the scraper arm require space for translation. Therefore, the range of translation of the scraper arm is limited in a small robot docking space, making it difficult to cover a large area of ​​the mop tray. However, the embodiment of this application uses a rotating scraper arm 200 (one end of the scraper arm 200 rotates while the other end moves). The scraper arm 200 only occupies a large space at the moving end, while the end of the scraper arm 200 that is rotatably connected to the base 100 does not occupy a large space. Therefore, using a rotating scraper arm 200 eliminates the need to leave a large space for the entire scraper arm 200. Consequently, in a small robot docking space, it is beneficial to cover a larger area of ​​the mop tray A1, thereby reducing cleaning dead corners and improving the cleaning ability of the corners and edges of the mop tray A1.

[0051] To improve the cleaning capability of the mop tray A1, the mop tray cleaning area may optionally include a filter area 101 and two cleaning areas 102 respectively distributed on both sides of the filter area 101, and each of the two cleaning areas 102 may be provided with a scraper arm 200.

[0052] The cleaning base station disclosed in this application divides the cleaning area of ​​the mop tray into a structure including a filter area 101 and two cleaning areas 102 respectively distributed on both sides of the filter area 101. Scraper arms 200 are correspondingly provided in the cleaning areas 102 on both sides, so that the mop tray A1 can be scraped by the two scraper arms 200, thereby improving the cleaning ability of the mop tray A1.

[0053] Optionally, the cleaning robot A can be configured with two mop discs A1, and two scraper arms 200 can cooperate with the two mop discs A1 respectively, so that the two mop discs A1 can be cleaned separately. Of course, the cleaning robot A can also be configured with only one mop disc A1, and the two scraper arms 200 can scrape different areas of the mop disc A1. The scraping area of ​​the two scraper arms 200 can cover the entire mop disc A1.

[0054] To collect wastewater generated during the scraping of the mop pad A1 by the scraper arm 200, the base 100 may optionally include a base body 110 and a water collection device 120, which may be detachably connected to the base body 110. The water collection device 120 may be located below the cleaning area of ​​the mop pad and is used to collect wastewater generated during the scraping of the mop pad A1.

[0055] The cleaning base station disclosed in this application sets the base 100 to include a base body 110 and a water receiving device 120, so that the water receiving device 120 is located below the mop tray cleaning area, thereby collecting the wastewater generated when cleaning the mop tray A1. By detachably connecting the water receiving device 120 to the base body 110, it is easy to remove the water receiving device 120 for cleaning (e.g., cleaning deposited dirt).

[0056] The water receiving device 120 can take many forms. For example, the entire water receiving device 120 can be a disc-shaped structure. The water receiving device 120 can include two filter elements. The filter elements can be vertically arranged along the disc surface of the water receiving device 120 (similar to the arrangement of a fence). The two filter elements divide the disc surface of the water receiving device 120 into three areas corresponding to the filtration area 101 and the two cleaning areas 102, respectively. The wastewater collected by the water receiving device 120 is stored or discharged after being filtered by the filter elements.

[0057] In another embodiment, the water receiving device 120 may include a device body 121 and a filter screen 122. The device body 121 may have a wastewater tank 121a, and the device body 121 may have water receiving trays 121b on both sides of the opening of the wastewater tank 121a. The water receiving trays 121b may communicate with the opening of the wastewater tank 121a. The wastewater tank 121a may be located below the filtration zone 101, and the water receiving trays 121b may be located below the cleaning zone 102. The water receiving trays 121b may be used to receive wastewater generated when cleaning the mop tray A1. The filter screen 122 may cover the opening of the wastewater tank 121a.

[0058] The cleaning base station disclosed in this application embodiment is configured with a water receiving device 120 including a device body 121 and a filter screen 122. The device body 121 has a sewage tank 121a. The device body 121 has water receiving trays 121b on both sides of the opening of the sewage tank 121a. The sewage tank 121a is located below the filtration area 101, and the water receiving trays 121b are located below the cleaning area 102. This allows the sewage generated by the scraper arm 200 scraping the mop pad A1 to fall into the water receiving trays 121b. The sewage received by the water receiving trays 121b is filtered by the filter screen 122 and then flows into the sewage tank 121a, thereby temporarily storing the sewage.

[0059] Specifically, the water receiving tray 121b may include a base plate 121b1, a baffle 121b2, and an inclined transition portion 121b3. The baffle 121b2 can be connected to the base plate 121b1 through the inclined transition portion 121b3. The side of the inclined transition portion 121b3 connected to the baffle 121b2 can be inclined upward toward the base plate 121b1.

[0060] The cleaning base station disclosed in this application configures the water receiving tray 121b as a structure including a base plate 121b1, a baffle 121b2, and an inclined transition portion 121b3, such that the side of the inclined transition portion 121b3 connected to the baffle 121b2 is inclined upward toward the base plate 121b1, so that sewage flows to the base plate 121b1 through the guiding effect of the inclined transition portion 121b3, thereby avoiding the baffle 121b2 being vertically connected to the base plate 121b1 and easily accumulating dirt at the corner of the connection, thereby reducing the cleaning frequency of the water receiving device 120 and helping to reduce the cleaning difficulty of the water receiving device 120.

[0061] In order to allow sewage to collect more effectively into the sewage tank 121a, the side of the bottom plate 121b1 away from the sewage tank 121a may be inclined upward towards the sewage tank 121a, thereby forming the bottom plate 121b1 as a guide surface inclined downward towards the sewage tank 121a, which makes it easier for sewage to collect into the sewage tank 121a.

[0062] When cleaning the sewage in the sewage tank 121a, the user can disassemble the water receiving device 120 and pour out the sewage.

[0063] In another embodiment, the device body 121 may have a water inlet communicating with the sewage tank 121a. The cleaning base station can use the water inlet to pump out the sewage in the sewage tank 121a, thereby cleaning the sewage in the sewage tank 121a. The side of the bottom wall of the sewage tank 121a away from the water inlet may be inclined upwards towards the sewage tank 121a, so that the sewage in the sewage tank 121a can converge towards the side of the water inlet, thereby making the sewage in the sewage tank 121a cleaner when the sewage is pumped out.

[0064] To facilitate the installation of the filter 122, the device body 121 may optionally have a first limiting protrusion 121c and a first engaging portion 121d. The first limiting protrusion 121c and the first engaging portion 121d may be located on both sides of the wastewater tank 121a. For example, the first limiting protrusion 121c and the first engaging portion 121d may be located on both sides in the direction of the cleaning robot A entering and exiting the robot docking space, and the first engaging portion 121d may be located on one side of the inlet / outlet of the robot docking space. The filter 122 may have a second engaging portion 122a. The end of the filter 122 facing away from the second engaging portion 122a may make upper contact with the first limiting protrusion 121c at the upper limit of the slot opening of the wastewater tank 121a, and the second engaging portion 122a may engage with the first engaging portion 121d.

[0065] The cleaning base station disclosed in this application provides a first limiting protrusion 121c and a first snap-fit ​​portion 121d on the device body 121, and a second snap-fit ​​portion 122a on the filter screen 122. This allows the end of the filter screen 122 facing away from the second snap-fit ​​portion 122a to make contact with the first limiting protrusion 121c at the upper limit of the opening of the sewage tank 121a. The second snap-fit ​​portion 122a engages with the first snap-fit ​​portion 121d, thereby making the filter screen 122 detachably connected to the device body 121 by snap-fit. This facilitates the removal of the filter screen 122 and, consequently, the cleaning of the sewage tank 121a.

[0066] To make the installation of the filter screen 122 more stable, the device body 121 may optionally have a first limiting groove 121e, and the first snap-fit ​​part 121d may be located in the first limiting groove 121e. When the second snap-fit ​​part 122a is snapped into place with the first snap-fit ​​part 121d, the second snap-fit ​​part 122a is limited to the first limiting groove 121e.

[0067] In the embodiments of this application, when the second snap-fit ​​portion 122a and the first snap-fit ​​portion 121d are engaged, the second snap-fit ​​portion 122a is confined within the first limiting groove 121e, thereby making the filter screen 122 more stably installed under the limiting effect of the second snap-fit ​​portion 122a and the first limiting groove 121e.

[0068] Of course, the filter screen 122 can also be installed in other ways. For example, the filter screen 122 can be installed on the device body 121 by bolts, magnets, etc. The embodiments of this application do not impose specific restrictions on the installation method of the filter screen 122.

[0069] When excessive sewage overflows from the sewage tank 121a into the water receiving tray 121b, the rotating scraper arm 200 can easily splash sewage onto the mop tray A1, resulting in poor cleaning of the mop tray A1. Therefore, it is necessary to avoid the sewage level in the sewage tank 121a from becoming too high. To avoid the sewage level in the sewage tank 121a from becoming too high, the filter screen 122 can optionally have a stepped portion 122b, which can form a liquid level detection space 122b1 with the inner wall of the sewage tank 121a. The cleaning base station B can also include a magnetic levitation element 500 and a Hall effect device. The magnetic levitation element 500 can be disposed in the liquid level detection space 122b1, and can be suspended above the sewage in the liquid level detection space 122b1. The Hall effect device can be used to determine the suspension height of the magnetic levitation element 500 based on the change in the magnetic field of the magnetic levitation element 500, and determine the sewage level by the suspension height.

[0070] The cleaning base station disclosed in this application configures the filter screen 122 with a stepped portion 122b, so that the stepped portion 122b and the inner wall of the sewage tank 121a form a liquid level detection space 122b1. This allows a magnetic levitation element 500 to be installed within the liquid level detection space 122b1. The levitation height of the magnetic levitation element 500 is determined by detecting changes in its magnetic field using a Hall effect device, and the sewage level is then determined based on this levitation height. When the sewage level reaches a preset level, the user is prompted to clean the sewage in the water-receiving device 120, or the cleaning base station automatically removes the sewage from the sewage tank 121a through a suction port, thereby preventing the sewage level in the sewage tank 121a from becoming too high.

[0071] Of course, in other embodiments, the cleaning base station can also detect the sewage level in the sewage tank 121a through a detection device such as a contact liquid level sensor or an infrared liquid level sensor. This application embodiment does not impose specific restrictions on the method of detecting the sewage level in the sewage tank 121a.

[0072] To make the disassembly and installation of the water receiving device 120 and the base body 110 more convenient, optionally, one of the water receiving device 120 and the base body 110 may be provided with a snap-fit ​​protrusion 111, and the other may be provided with a snap-fit ​​hole 120a. The water receiving device 120 can be detachably connected to the base body 110 through the snap-fit ​​engagement of the snap-fit ​​protrusion 111 and the snap-fit ​​hole 120a.

[0073] Specifically, when installing the water receiving device 120 and the base body 110, the user can push the water receiving device 120 to move so that the snap-fit ​​protrusion 111 engages with the snap-fit ​​hole 120a, thereby realizing the installation of the water receiving device 120 and the base body 110. When disassembling the water receiving device 120 and the base body 110, the user can apply an external force along the separation direction of the water receiving device 120 and the base body 110 to disassemble the water receiving device 120 and the base body 110.

[0074] Of course, in another embodiment, an elastic element can be connected between the water receiving device 120 and the base body 110. After the water receiving device 120 and the base body 110 are installed, the elastic element can store elastic force. When the water receiving device 120 and the base body 110 are disassembled, the user can also manually press the fastening protrusion 111 to separate the fastening protrusion 111 from the fastening hole 120a. Thus, under the elastic force of the elastic element, the water receiving device 120 and the base body 110 will automatically spring open, thereby completing the disassembly of the water receiving device 120 and the base body 110.

[0075] It should be noted that the water receiving device 120 and the base body 110 at the position of the fastening protrusion 111 and the fastening hole 120a can be structures with a certain degree of elastic deformation or plastic deformation.

[0076] The clean base station B disclosed in this application embodiment allows the water receiving device 120 and the base body 110 to be detachably connected by a fastening protrusion 111 and a fastening hole 120a. This makes the disassembly and installation of the water receiving device 120 and the base body 110 more convenient. Since the structure of the fastening protrusion 111 and the fastening hole 120a is relatively simple, it helps to simplify the structure of the water receiving device 120 and the base body 110.

[0077] To ensure that the water receiving device 120 is installed in place with the base body 110, the water receiving device 120 may optionally be provided with a fourth position detection element 112, which can be used to detect whether the water receiving device 120 is installed in place when it is installed on the base body 110.

[0078] The clean base station disclosed in this application embodiment is equipped with a fourth position detection element 112, which can detect whether the water receiving device 120 is installed in place when it is installed on the base body 110, thereby ensuring that the water receiving device 120 and the base body 110 are installed in place.

[0079] Specifically, the fourth position detection element 112 may include a detection lever 112a and a micro switch 112b. The detection lever 112a is rotatable, and the micro switch 112b is disposed adjacent to the first end of the detection lever 112a. The water receiving device 120 may be provided with a lever triggering part 121f. When the fastening protrusion 111 is engaged with the fastening hole 120a, the lever triggering part 121f can contact the second end of the detection lever 112a and push the detection lever 112a to rotate, so that the first end of the detection lever 112a contacts the micro switch 112b, thereby triggering the micro switch 112b. The cleaning base station B can confirm whether the water receiving device 120 and the base body 110 are properly installed based on the state of the micro switch 112b (including the triggered state and the non-triggered state). If the water receiving device 120 is not properly installed between the base body 110 and the cleaning base station B, the cleaning base station B can issue a prompt message to remind the user that the water receiving device 120 is not properly installed between the base body 110, so that the user can reinstall it.

[0080] Of course, the fourth position detection element 112 can also be a limit switch, an infrared distance detection element, etc. The embodiments of this application do not impose specific limitations on the structure of the fourth position detection element 112.

[0081] To facilitate the entry and exit of the cleaning robot A into and out of the robot docking space of the cleaning base station B, the base 100 may optionally include an entry ramp 130. The entry ramp 130 can be connected to the water receiving device 120. The cleaning robot A can enter and exit the cleaning base station B through the entry ramp 130. At least part of the entry ramp 130 is inclined and extended to facilitate the connection with the ground of the environment where the cleaning base station B is located, which is beneficial for the entry and exit of the cleaning robot A.

[0082] This application also discloses a cleaning system, which includes a cleaning robot A and a cleaning base station B disclosed in the above embodiments, wherein the cleaning robot A cooperates with the cleaning base station B.

[0083] The cleaning system disclosed in this application, by setting up the cleaning base station B as disclosed in the above embodiment, allows interference between the scraper arm 200 and the mop tray A1 when the cleaning robot A is docked at the cleaning base station B. During rotation, the scraper arm 200 scrapes away wastewater from the mop tray A1 through this interference. Because the cleaning base station B uses the rotation of the scraper arm 200 to scrape the mop tray A1, the range of motion of the scraper arm 200 is no longer limited by the length of the rack. This allows the scraper arm 200 to cover a larger area of ​​the mop tray A1 in a relatively small space, thereby improving the cleaning ability of the cleaning base station B to clean the corners and edges of the mop tray A1.

[0084] Example 2:

[0085] Please refer to Figures 1 to 16. This application discloses a cleaning base station B, which can be used in conjunction with a cleaning robot A. Specifically, the cleaning base station B has a robot docking space for the cleaning robot A to dock. When the cleaning robot A is docked in the robot docking space, the cleaning base station B can at least charge the cleaning robot A and clean the mop tray A1 of the cleaning robot A.

[0086] The cleaning base station B may include a base 100, a scraper arm 200, and a drive mechanism 300.

[0087] The base 100 can be the mounting base for at least some of the components of the cleaning base station B, and can also be used to collect the wastewater scraped off the mop disc A1 by the scraper arm 200 (the wastewater referred to here is a broad category, including foreign objects in the water, such as hair, sunflower seed shells, etc.).

[0088] The drive mechanism 300 includes a drive member 310, a transmission member 320, and a synchronous pulley 330. The synchronous pulley 330 is rotatably mounted on the base 100. One end of the scraper arm 200 is fixedly connected to the synchronous pulley 330. The drive member 310 is mounted on the base 100 and connected to the transmission member 320, and is used to drive the synchronous pulley 330 to rotate the scraper arm 200 through the transmission member 320.

[0089] When the cleaning robot A is parked at the cleaning base station B, the mop disc A1 of the cleaning robot A is located in the mop disc cleaning area of ​​the base 100. The drive unit 310 can drive the synchronous wheel 330 through the transmission unit 320 to drive the scraper arm 200 to rotate, so that the scraper arm 200 scrapes the mop disc A1.

[0090] The cleaning base station B disclosed in this application embodiment configures the drive mechanism 300 as including a drive member 310, a transmission member 320, and a synchronous wheel 330. The synchronous wheel 330 is rotatably mounted on the base 100, and one end of the scraper arm 200 is fixedly connected to the synchronous wheel 330. This allows the drive member 310 to drive the synchronous wheel 330 to rotate the scraper arm 200 via the transmission member 320. The scraper arm 200 scrapes away the wastewater on the mop pad A1 through interference with the mop pad A1. Because the cleaning base station B disclosed in this application embodiment uses the drive member 310 to drive the synchronous wheel 330 via the transmission member 320 to rotate the scraper arm 200 to scrape the mop pad A1, the range of motion of the scraper arm 200 is no longer limited by the length of the rack. This allows the scraper arm 200 to cover a larger area of ​​the mop pad A1 in a relatively small space, thereby improving the cleaning ability of the cleaning base station B to clean the corners and edges of the mop pad A1.

[0091] Specifically, the transmission component 320 can be a transmission belt, and the synchronous pulley 330 can be a synchronous belt pulley. Of course, the transmission component 320 can also be a transmission chain, and the synchronous pulley 330 can be a synchronous sprocket. This application embodiment does not impose specific limitations on the specific forms of the transmission component 320 and the synchronous pulley 330. The drive component 310 can be a hydraulic drive mechanism, a pneumatic drive mechanism, a drive motor, etc. This application embodiment does not impose specific limitations on the type of drive component 310.

[0092] Optionally, the drive mechanism 300 may also include multiple idler wheels 340, which are rotatably mounted on the base 100. Two idler wheels 340 may be provided on the same side of the synchronous pulley 330. The synchronous pulley 330 and multiple idler wheels 340 may be connected by a transmission member 320.

[0093] When the transmission component 320 uses a transmission belt, the synchronous pulley 330 is a synchronous belt pulley. Referring to Figure 11, the transmission belt first passes over one of the two idler pulleys 340, then over the corresponding synchronous belt pulley, and finally over the other idler pulley 340. This installation method increases the contact area between the transmission belt and the synchronous belt pulley, thereby mitigating slippage between them.

[0094] When the transmission component 320 uses a transmission chain, the synchronizing pulley 330 is a synchronizing sprocket. The transmission chain first passes around one of the two idler pulleys 340, then around the corresponding synchronizing sprocket, and then around the other idler pulley 340. This method of installation increases the contact area between the transmission chain and the synchronizing sprocket, thus preventing the risk of the transmission chain disengaging from the synchronizing sprocket.

[0095] When the base 100 has a mop disc cleaning area, which includes a filter area 101 and two cleaning areas 102 respectively distributed on both sides of the filter area 101, there can be two scraper arms 200 and two synchronous pulleys 330. The two scraper arms 200 can be correspondingly arranged on the two cleaning areas 102. Each synchronous pulley 330 can have two idler pulleys 340 on the same side. The two synchronous pulleys 330 and the multiple idler pulleys 340 are connected by a transmission component 320, so that the two scraper arms 200 can rotate synchronously.

[0096] To facilitate the installation of the transmission component 320, optionally, at least one of the plurality of idler wheels 340 can be a tensioner wheel 340a, which can be used to tension the transmission component 320.

[0097] Specifically, when installing the transmission component 320, the tensioner 340a can be initially in the released state to facilitate installation. After installation, the tensioner 320 can be tensioned by adjusting the tensioner 340a, thereby enabling the transmission component 320 to drive the synchronous pulley 330 and the idler pulley 340. Furthermore, the tensioner 340a can also be used to adjust the tension of the transmission component 320, thus preventing slippage between the transmission component 320 and the synchronous pulley 330 or separation between them.

[0098] This application discloses a specific structure of a tensioning wheel 340a. The tensioning wheel 340a may include a first wheel body 340a1, a first mounting shaft 340a2, and an adjusting bracket 340a3. The first mounting shaft 340a2 may be disposed on the base 100. The first wheel body 340a1 is rotatably sleeved on the first mounting shaft 340a2. The first end of the adjusting bracket 340a3 may be connected to the first mounting shaft 340a2, and the second end of the adjusting bracket 340a3 is rotatably sleeved on the mounting post 140 of the base 100. When the adjusting bracket 340a3 moves along the mounting post 140 to a first height, the second end of the adjusting bracket 340a3 may rotate relative to the mounting post 140.

[0099] When the adjusting bracket 340a3 moves to the second height along the mounting column 140, the second end of the adjusting bracket 340a3 can make a limiting contact with the base 100 to restrict the rotation of the adjusting bracket 340a3. The second height of the adjusting bracket 340a3 on the mounting column 140 is the position where the tensioning wheel 340a is fixedly installed after the tension is adjusted.

[0100] Specifically, the second end of the adjusting bracket 340a3 may have a bracket limiting portion, and the base 100 may have a bracket limiting groove at the second height position of the mounting column 140. The base 100 does not have a bracket limiting groove at the first height position of the mounting column 140. When the adjusting bracket 340a3 moves along the mounting column 140 to the first height, the second end of the adjusting bracket 340a3 can rotate relative to the mounting column 140. When the adjusting bracket 340a3 moves along the mounting column 140 to the second height, the bracket limiting portion can move into the bracket limiting groove, thereby restricting the rotation of the adjusting bracket 340a3. Of course, the limiting contact between the second end of the adjusting bracket 340a3 and the base 100 can also be in other ways, and this embodiment does not impose specific limitations on this.

[0101] In other embodiments, the tensioning wheel 340a may also include a first wheel body 340a1, a first mounting shaft 340a2, and a telescopic member. The telescopic member may be disposed on the base 100, the first mounting shaft 340a2 may be disposed on the telescopic member, and the first wheel body 340a1 may be rotatably disposed on the first mounting shaft 340a2. The telescopic member can drive the first wheel body 340a1 to move through telescopic movement, thereby adjusting the tension of the transmission member 320. Of course, the tensioning wheel 340a may also have other structures, and the embodiments of this application do not specifically limit the structure of the tensioning wheel 340a.

[0102] Specifically, the second mounting shaft 332 of the synchronous pulley 330 can be fixedly mounted on the base 100, and the synchronous pulley 330 can be rotatably mounted on the second mounting shaft 332.

[0103] In another embodiment, the drive mechanism 300 may further include a first bearing 350 and a second bearing 360. The synchronous wheel 330 may include a second wheel body 331 and a second mounting shaft 332. The second wheel body 331 may be fixedly sleeved on the second mounting shaft 332. The two ends of the second mounting shaft 332 may be rotatably mounted on the base 100 through the first bearing 350 and the second bearing 360, respectively. The scraper arm 200 may be fixedly connected to the second mounting shaft 332.

[0104] The cleaning base station disclosed in this application adopts a structure in which the two ends of the second mounting shaft 332 are rotatably mounted on the base 100 via the first bearing 350 and the second bearing 360 respectively, and the second wheel body 331 is fixedly sleeved on the second mounting shaft 332. This structure makes the installation of the second mounting shaft 332 more stable, which in turn is beneficial to the stability of the scraper arm 200 when it rotates.

[0105] In an optional embodiment, the base 100 may have a mop tray cleaning area, which may include a filter area 101 and two cleaning areas 102 respectively distributed on both sides of the filter area 101. There may be two scraper arms 200 and two synchronous pulleys 330. The two scraper arms 200 may be correspondingly located on the two cleaning areas 102, and the two synchronous pulleys 330 may be connected by a transmission member 320. One end of the scraper arm 200 connected to the synchronous pulley 330 has a trigger part 250. The cleaning base station B may also include a first position detection member 410 and a second position detection member 420. The two scraper arms 200 may be a first scraper arm and a second scraper arm, respectively. When the two scraper arms 200 rotate in a first direction until the trigger part 250 is in the position that triggers the first position detection member 410, the first scraper arm is located on the side of the corresponding cleaning area 102 away from the filter area 101, and the second scraper arm is located on the side of the corresponding cleaning area 102 closer to the filter area 101. When the two scraper arms 200 rotate in the second direction until the trigger part 250 is in the position of triggering the second position detection element 420, the second scraper arm is located on the side of the corresponding cleaning area 102 away from the filter area 101, and the first scraper arm is located on the side of the corresponding cleaning area 102 closer to the filter area 101. The first direction is opposite to the second direction.

[0106] It should be noted that the two scraper arms 200 can be connected by the transmission component 320, so that the two scraper arms 200 can rotate synchronously and in the same direction. When the triggering unit 250 triggers the first position detection component 410 or the second position detection component 420, the driving component 310 will drive the scraper arm 200 to start rotating in the opposite direction, so that the scraper arm 200 reciprocates within a preset angle range.

[0107] The cleaning base station B disclosed in this application sets the cleaning area of ​​the mop tray to include a filter area 101 and two cleaning areas 102 respectively distributed on both sides of the filter area 101. The two scraper arms 200 are correspondingly located in the cleaning areas 102 on both sides, so that the two scraper arms 200 can scrape the mop tray A1, thereby improving the scraping ability of the mop tray A1. By setting a trigger part 250 at one end of the scraper arm 200 connected to the synchronous wheel 330, and setting a first position detection element 410 and a second position detection element 420 on the cleaning base station B, when the two scraper arms 200 rotate in the first direction to the position where the trigger part 250 triggers the first position detection element 410, the first scraper arm is located on the side of the corresponding cleaning area 102 away from the filter area 101, and the second scraper arm is located on the side of the corresponding cleaning area 102 close to the filter area 101. When the two scraper arms 200 rotate in the second direction to the position where the trigger part 250 triggers the second position detection element 420, the second scraper arm is located on the side of the corresponding cleaning area 102 away from the filter area 101, and the first scraper arm is located on the side of the corresponding cleaning area 102 close to the filter area 101. This allows the scraper arms 200 to rotate within a preset angle range within the cleaning area of ​​the mop disc, preventing the scraper arms 200 from rotating outside the mop disc A1 and performing ineffective movements, thereby improving the scraping efficiency of the mop disc A1.

[0108] Optionally, the cleaning base station B may also include a third position detection element 430, in which the two scraper arms 200 are located in the middle of the corresponding cleaning area 102 when the triggering unit 250 triggers the third position detection element 430.

[0109] It should be noted that in the embodiment where the base 100 includes a base body 110 and a water receiving device 120, and the water receiving device 120 includes a device body 121 and a filter screen 122, if the scraper arm 200 is located above the filter screen 122 when it is necessary to remove the filter screen 122, the scraper arm 200 will block the filter screen 122 and make it inconvenient to remove the filter screen 122. However, the cleaning base station B disclosed in this application embodiment, by setting a third position detection element 430, allows the scraper arm 200 to stop at the position where the trigger part 250 triggers the third position detection element 430 when it is necessary to remove the filter screen 122. This ensures that both scraper arms 200 are located in the middle of the corresponding cleaning area 102, avoiding the filter screen 122, thereby facilitating the removal of the filter screen 122.

[0110] The first position detection element 410, the second position detection element 420, and the third position detection element 430 can all be photoelectric sensors, which helps to improve the detection sensitivity of the first position detection element 410, the second position detection element 420, and the third position detection element 430.

[0111] Of course, the first position detection element 410, the second position detection element 420 and the third position detection element 430 can also be micro switches, limit switches, etc. The embodiments of this application do not impose specific restrictions on the types of the first position detection element 410, the second position detection element 420 and the third position detection element 430.

[0112] To protect the drive mechanism 300, the base 100 may optionally have a mop pad cleaning area, and the scraper arm 200 may be located in the mop pad cleaning area. A receiving groove 103 may be provided on the side of the base 100 away from the scraper arm 200 (the side of the base 100 away from the scraper arm 200 refers to the side of the base 100 facing the ground when the base 100 is placed on the ground). At least a portion of the transmission member 320 and the synchronous pulley 330 may be located in the receiving groove 103, and the second mounting shaft 332 of the synchronous pulley 330 may pass through the base 100 and be connected to the scraper arm 200.

[0113] The clean base station B disclosed in this application provides at least a portion of the transmission member 320 and the synchronous wheel 330 within the receiving groove 103, thereby protecting at least a portion of the transmission member 320 and the synchronous wheel 330. Furthermore, the receiving groove 103 can also prevent sewage from corroding the portions of the transmission member 320 and the synchronous wheel 330 located within the receiving groove 103.

[0114] This application also discloses a cleaning system, which includes a cleaning robot A and a cleaning base station B disclosed in the above embodiments, wherein the cleaning base station B cooperates with the cleaning robot A.

[0115] The cleaning system disclosed in this application embodiment, by setting up the cleaning base station B disclosed in the above embodiment, enables the drive unit 310 to drive the synchronous wheel 330 to rotate via the transmission unit 320. The scraper arm 200 scrapes away the sewage on the mop disc A1 through interference with the mop disc A1. Since the cleaning base station B disclosed in this application embodiment uses the drive unit 310 to drive the synchronous wheel 330 via the transmission unit 320 to rotate the scraper arm 200 to scrape the mop disc A1, the range of motion of the scraper arm 200 is no longer limited by the length of the rack. This allows the scraper arm 200 to cover a larger area of ​​the mop disc A1 in a relatively small space, thereby improving the cleaning ability of the cleaning base station B to clean the corners and edges of the mop disc A1.

[0116] Example 3:

[0117] Please refer to Figures 1 to 16. This application also discloses a scraper arm 200, which can be applied to the cleaning base station B disclosed in the above embodiments.

[0118] The scraper arm 200 may include a scraper arm body 210, which includes a first scraper strip 211 and a second scraper strip 212. Both the first scraper strip 211 and the second scraper strip 212 extend along the length of the scraper arm body 210 and are located on opposite sides of the scraper arm body 210 in the height direction, with the first scraper strip 211 positioned above the second scraper strip 212. The first end of the scraper arm 200 can be rotatably connected to the base 100.

[0119] The base 100 of the cleaning base station B includes a base body 110 and a water receiving device 120. The device body 121 of the water receiving device 120 has a sewage tank 121a. When a water receiving tray 121b is set at the opening of the sewage tank 121a, when the cleaning robot A is parked in the robot parking space of the cleaning base station B, the first scraper 211 is used to scrape the mop disc A1 of the cleaning robot A, and the sewage scraped off the mop disc A1 falls into the water receiving tray 121b. The second scraper 212 is used to scrape the sewage received by the water receiving tray 121b into the sewage tank 121a. The first scraper 211 scrapes the mop disc A1 and the second scraper 212 scrapes the water receiving tray 121b simultaneously, thereby realizing the simultaneous cleaning of the mop disc A1 and the water receiving tray 121b.

[0120] The scraper arm 200 disclosed in this application embodiment is configured with a scraper arm body 210 including a first scraper 211 and a second scraper 212. When the cleaning robot A is docked in the robot docking space of the cleaning base station B, the scraper arm 200 rotates around its first end. The first scraper 211 scrapes the mop disc A1 of the cleaning robot A, and the second scraper 212 scrapes the sewage received by the water receiving tray 121b into the sewage tank 121a. Thus, the cleaning of the water receiving tray 121b and the mop disc A1 can be achieved by a single scraper arm 200, eliminating the need for a separate structure for cleaning the water receiving tray 121b, which is beneficial to the compactness of the cleaning base station B.

[0121] Specifically, the first scraper 211 can be a scraper blade, and the second scraper 212 can be a rubber scraper blade. Of course, both the first scraper 211 and the second scraper 212 can be scraper blades or rubber scraper blades. This application embodiment does not limit the structure of the first scraper 211 and the second scraper 212. When the second scraper 212 is a rubber scraper blade, a portion of the second scraper 212 is disposed on the back plate 214, which can fix and reinforce the second scraper 212. A scraper blade is a rigid plate with a certain strength, unlike a rubber scraper blade, which is a structural component with a certain degree of flexibility.

[0122] To prevent excessive wastewater from being scraped away from the wastewater tank 121a when the second scraper 212 moves along the side away from the wastewater tank 121a, the second scraper 212 may optionally include a scraper body 212a and a folded portion 212b. The folded portion 212b is used to interfere with the water receiving tray 121b. The folded portion 212b may be located on the side of the scraper body 212a opposite to the first scraper 211. The folded portion 212b may be folded towards the first side of the scraper body 210 in the width direction. The first side and the second side of the scraper body 210 are distributed opposite to each other. The first side of the scraper body 210 refers to the side of the scraper body 210 facing the wastewater tank 121a.

[0123] When the scraper arm 200 rotates along the side away from the sewage tank 121a, the folding part 212b folds over the first side of the scraper arm body 210 in the width direction, so that the sewage on the water receiving tray 121b can pass between the folding part 212b and the water receiving tray 121b, thereby reducing the amount of water that is scraped away from the sewage tank 121a. When the scraper arm 200 rotates along the side close to the sewage tank 121a, the folding part 212b does not fold over, and the folding part 212b and the water receiving tray 121b have stable interference, so that the sewage on the water receiving tray 121b can be scraped into the sewage tank 121a.

[0124] To further reduce the amount of sewage that the second scraper 212 scrapes away from the sewage tank 121a, the second scraper 212 may optionally include an avoidance protrusion 212c. The avoidance protrusion 212c may be provided on the folded portion 212b and may be located on the second side of the scraper arm body 210, with the first side of the scraper arm body 210 and the second side of the scraper arm body 210 being distributed opposite to each other.

[0125] The scraper arm 200 disclosed in this application has an avoidance protrusion 212c on the second side of the folded portion 212b. When the scraper arm 200 rotates along the side away from the sewage tank 121a, the avoidance protrusion 212c interferes with the water receiving tray 121b, thereby supporting the folded portion 212b at a position spaced apart from the water receiving tray 121b. This can better reduce the amount of sewage scraped by the second scraper 212 to the side away from the sewage tank 121a.

[0126] Optionally, there can be multiple clearance protrusions 212c, which can be spaced apart along the length of the scraper arm body 210. When the scraper arm 200 rotates along the side away from the sewage tank 121a, the multiple clearance protrusions 212c support the folding part 212b, thereby preventing the folding part 212b from partially falling onto the water receiving tray 121b due to its long length.

[0127] When the scraper arm body 210 first comes into contact with the mop tray A1 of the cleaning robot A, in order to prevent the first scraper bar 211 from snagging the mop on the mop tray A1 from the edge, the scraper arm body 210 may optionally include a guide protrusion 213. The guide protrusion 213 may be located on the first side of the scraper arm body 210. The guide protrusion 213 may have a guide surface 213a. One end of the guide surface 213a may extend to the top of the first scraper bar 211, and the other end of the guide surface 213a may extend obliquely toward the side below the top of the first scraper bar 211.

[0128] The scraper arm 200 disclosed in this application embodiment is provided with a guide protrusion 213, and one end of the guide surface 213a of the guide protrusion 213 extends to the top of the first scraper 211, and the other end of the guide surface 213a extends obliquely towards the side below the top of the first scraper 211. This allows the first scraper 211 to enter from the edge of the mop under the guidance of the guide surface 213a when the scraper arm body 210 just comes into contact with the mop tray A1 of the cleaning robot A. This prevents the first scraper 211 from snagging the mop on the mop tray A1 from the edge.

[0129] Optionally, there can be multiple guide protrusions 213, and the multiple guide protrusions 213 can be distributed at intervals along the length direction of the scraper body 210.

[0130] The scraper arm 200 disclosed in this application can better prevent the first scraper bar 211 from snagging the mop on the mop tray A1 from the edge by providing a plurality of guide protrusions 213 spaced apart along the length direction of the scraper arm body 210.

[0131] To prevent the wastewater scraped off the mop disc A1 by the first scraper 211 from accumulating on the scraper body 210 and causing it to get dirty easily, the scraper body 210 may optionally be provided with a guide hole 201. The guide hole 201 can extend from the side where the first scraper 211 is located to the side where the second scraper 212 is located. This allows the wastewater scraped off the mop disc A1 by the first scraper 211 to accumulate on the scraper body 210, so that when the wastewater accumulates on the scraper body 210, it can fall onto the water receiving tray 121b through the guide hole 201, thereby alleviating the problem of the scraper body 210 getting dirty easily.

[0132] Furthermore, the scraper arm body 210 may also have a guide groove 202, the opening of the guide groove 202 may face the side where the first scraper bar 211 is located, and the guide groove 202 may be connected to the guide hole 201.

[0133] The scraper arm 200 disclosed in this application has a guide groove 202 on the scraper arm body 210, and the guide groove 202 is connected to the guide hole 201. This allows the wastewater scraped off from the mop disc A1 by the first scraper bar 211 to flow through the guide groove 202 to the guide hole 201 when it collects on the scraper arm body 210, thereby better alleviating the problem of wastewater collecting on the scraper arm body 210.

[0134] To better clean the mop disc A1, the scraper arm 200 may optionally include a water spray pipe 220. The water spray pipe 220 may be located on the scraper arm body 210 and may extend along the length of the scraper arm body 210. The water spray pipe 220 may have multiple water spray nozzles 221 spaced apart along the length of the scraper arm body 210, and the water spray nozzles 221 may be directed toward the side where the first scraper bar 211 is located.

[0135] Before or during the first scraper 211 scrapes the mop disc A1, the water spray pipe 220 can spray water onto the mop disc A1 (the mop on the mop disc A1) through the water spray nozzle 221, thereby improving the cleaning effect on the mop disc A1.

[0136] The base 100 includes a base body 110 and a water receiving device 120. The water receiving device 120 is detachably connected to the base body 110. The device body 121 of the water receiving device 120 has a sewage tank 121a. The device body 121 has a water receiving tray 121b on both sides of the opening of the sewage tank 121a. When the water receiving tray 121b is connected to the opening of the sewage tank 121a, in order to avoid the problem that the scraper arm body 210 is pressed on the water receiving tray 121b and thus the water receiving device 120 is inconvenient to disassemble, the scraper arm 200 may optionally include a bearing seat 240. The first end of the scraper arm body 210 may be connected to the bearing seat 240, the second end of the scraper arm body 210 may be a free end, the bearing seat 240 may be a rotating end of the scraper arm 200, and the bearing seat 240 may be fixedly connected to the second mounting shaft 332 disclosed in the above embodiment.

The first scraper 211 is used to scrape the mop tray A1 of the cleaning robot A, and the second scraper 212 is used to scrape the sewage falling into the cleaning area 102 into the filter area 101 (that is, the second scraper 212 is used to scrape the sewage falling into the water receiving tray 121b of the cleaning area 102 into the sewage tank 121a of the filter area 101).

[0141] The cleaning base station disclosed in this application, by setting up the scraper arm 200 disclosed in the above embodiment, enables the first scraper blade 211 to scrape the mop disc A1 of the cleaning robot A when the cleaning robot A is docked in the robot docking space of the cleaning base station B, and the second scraper blade 212 to scrape the sewage received by the water receiving tray 121b into the sewage tank 121a when the scraper arm 200 rotates around its first end. Thus, the cleaning of the water receiving tray 121b and the mop disc A1 can be achieved by one scraper arm 200, so that there is no need to set up a separate structure for cleaning the water receiving tray 121b, which is beneficial to the compactness of the cleaning base station B.

[0142] This application also discloses a cleaning system, which includes a cleaning robot A and a cleaning base station B disclosed in the above embodiments, wherein the cleaning robot A and the cleaning base station B cooperate.

[0143] The cleaning system disclosed in this application, by setting up the cleaning base station B disclosed in the above embodiments, enables the first scraper 211 to scrape the mop disc A1 of the cleaning robot A when the cleaning robot A is docked in the robot docking space of the cleaning base station B, and the second scraper 212 to scrape the sewage received by the water receiving tray 121b into the sewage tank 121a when the scraper arm 200 rotates around its first end. Thus, the cleaning of the water receiving tray 121b and the mop disc A1 can be achieved by one scraper arm 200, thereby eliminating the need to set up a separate structure for cleaning the water receiving tray 121b, which is beneficial to the compactness of the cleaning base station B.
