[0053] In this application, the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0054] The embodiment of the present application provides a cleaning head 10 , a cleaning device 100 , and a cleaning system 1000 , wherein the cleaning head 10 is at least used for the cleaning device 100 .

[0055] The cleaning system 1000 includes a cleaning base station 200 and a cleaning device 100, wherein the cleaning base station 200 is at least used to park the cleaning device 100. When the cleaning device 100 is in operation, it can directly contact the surface to be cleaned and perform cleaning treatment on the surface to be cleaned.

[0056] For example, the surface to be cleaned may be a floor, and the cleaning device 100 may be a floor scrubber, a sweeping and mopping robot, a mopping robot, a steam mop, or other floor cleaning tools for cleaning the floor. If the surface to be cleaned is a wall or a window, the cleaning device 100 may be a window cleaner.

[0057] For example, a floor scrubber is used as cleaning device 100. This scrubber is suitable for cleaning hard surfaces and can perform dust collection, mopping, and cleaning functions. The cleaning device 100 includes a connected cleaning head 10 and a main body. The cleaning head 10 is designed to directly contact the surface to be cleaned, while the main body is designed to be held by the user. When the cleaning device 100 is placed on a cleaning base station 200, the cleaning head 10 directly contacts the base station, allowing the cleaning base station 200 to clean the cleaning device 100.

[0058] The cleaning head 10 has a front side and a rear side when in use, wherein the bottom surface of the cleaning head 10 for directly contacting the surface to be cleaned is provided with a cleaning member 21 (such as a cleaning brush, etc.), and the cleaning member 21 is provided with a cleaning scraper 22 (that is, the cleaning scraper 22 is a front scraper) on the outside toward the front side, and the cleaning scraper 22 can be raised and lowered relative to the cleaning member 21 to rise or fall relative to the cleaning member 21. When the cleaning head 10 moves toward the front side and cleans the surface to be cleaned, the cleaning member 21 can directly contact the surface to be cleaned and clean the surface to be cleaned. At this time, the cleaning scraper 22 rises relative to the cleaning member 21 so that there is a larger ground clearance between it and the surface to be cleaned, avoiding the cleaning scraper 22 from directly contacting the surface to be cleaned, thereby avoiding the jamming problem caused by the cleaning scraper 22 directly contacting large-sized garbage on the ground, so that the cleaning head 10 can move smoothly toward its front side; when the cleaning head 10 moves toward the rear side and cleans the surface to be cleaned, the cleaning scraper 22 descends relative to the cleaning member 21 and directly contacts the surface to be cleaned to achieve scraping treatment of the surface to be cleaned. At this time, the cleaning scraper 22 can effectively scrape the dirt and water stains attached to the surface to be cleaned, so as to help improve the cleaning efficiency and cleaning effect of the cleaning head 10 on the surface to be cleaned.

[0059] During the reciprocating cleaning process of the cleaning head 10 moving forward and backward multiple times, a certain amount of garbage will be attached to the outer surface of the cleaning strip 22 facing the front side. In the case of garbage attached, if the cleaning strip 22 rises as the cleaning head 10 moves forward, the above-mentioned garbage will enter the interior of the outer shell of the cleaning head 10 as the cleaning strip 22 rises, causing the cleaning strip 22 to be contaminated. In addition, when the cleaning strip 22 is extended again as the cleaning head 10 moves backward, some of the garbage will fall as the cleaning strip 22 is extended, causing secondary contamination of the surface to be cleaned. In addition, the above-mentioned garbage attached to the front surface of the cleaning strip 22 will also contaminate the user's furniture, walls, etc. during use, and to a certain extent reduce the user's experience.

[0060] In order to improve the above problems and enhance the user experience to a certain extent, an embodiment of the present application provides a cleaning head 10, which is at least used for the above-mentioned cleaning device 100 and a cleaning system 1000 having the cleaning device 100.

[0061] See also Figure 1 and Figure 2 , Figure 1 This is a schematic structural diagram of the cleaning head 10 provided in an embodiment of the present application. Figure 2 This is a partial structural diagram of the cleaning head 10 provided in an embodiment of the present application.

[0062] The cleaning head 10 provided in the embodiment of the present application includes a housing 1, a cleaning unit 2 and a scraping member 3, wherein the cleaning unit 2 includes the cleaning member 21 and the cleaning scraping bar 22 mentioned above, the cleaning member 21 is rotatably arranged in the housing 1 for cleaning the surface to be cleaned, and the cleaning scraping bar 22 is arranged on the front side of the cleaning member 21 and can move up and down relative to the cleaning member 21, so as to scrape and clean the surface to be cleaned when it is lowered relative to the cleaning member 21 to contact the surface to be cleaned. The above-mentioned scraping member 3 is arranged on the side of the cleaning scraping bar 22 facing away from the cleaning member 21. When the cleaning scraping bar 22 moves up and down relative to the cleaning member 21, in response to the movement of the cleaning scraping bar 22, the scraping member 3 and the cleaning scraping bar 22 generate relative movement and cover at least part of the surface of the front side of the cleaning scraping bar 22.

[0063] See also Figure 1 and Figure 2 The scraping member 3 is mounted on the housing 1 and is located in front of the cleaning bar 22. As the cleaning bar 22 moves up and down, the relative position between the scraping member 3 and the cleaning bar 22 changes, and the area of ​​the cleaning bar 22 covered by the scraping member 3 gradually increases as the cleaning bar 22 rises.

[0064] At least part of the scraping member 3 is located on the lifting path of the cleaning strip 22. Figure 3 , Figure 3for Figure 2 In response to the lifting movement of the cleaning strip 22 , the scraping member 3 and the front surface of the cleaning strip 22 generate relative friction to receive or release the cleaning strip 22 .

[0065] When the cleaning strip 22 rises relative to the cleaning member 21, the scraping member 3 can scrape the surface of the cleaning strip 22 by generating relative friction with the front surface of the cleaning strip 22, helping to remove dirt attached to the front surface of the cleaning strip 22. When the cleaning strip 22 rises to its highest position, the scraping member 3 can accommodate the cleaning strip 22. Figure 3 At this time, the front side surface of the cleaning strip 22 has been completely covered by the scraping member 3, or has been substantially covered by the scraping member 3.

[0066] That is, as the cleaning bar 22 rises relative to the cleaning member 21, the area of ​​the front side of the cleaning bar 22 covered by the scraping member 3 gradually increases. In response to the upward movement of the cleaning bar 22, the scraping member 3 can contact at least a portion of the surface of the front side of the cleaning bar 22 and be accommodated inside the scraping member 3.

[0067] When the cleaning strip 22 descends relative to the cleaning member 21, the scraping member 3 can maintain contact with the front surface of the cleaning strip 22 by friction with the front surface of the cleaning strip 22 to prevent external dirt from entering the top of the cleaning strip 22 through the gap between the cleaning strip 22 and the scraping member 3.

[0068] For example, when the cleaning strip 22 is in the working position, that is, when it is close to and in contact with the surface to be cleaned, the scraping member 3 can be in contact with the front surface of the cleaning strip 22 near the top or the top surface and at least cover the top of the cleaning strip 22, thereby sealing the space above the cleaning strip 22. At this time, when the cleaning head 10 is performing a cleaning operation, the scraping member 3 can act as a barrier to prevent foreign matter from contacting and entering the top of the cleaning strip 22, thereby ensuring that the space above the cleaning strip 22 is clean.

[0069] When the cleaning strip 22 is away from the surface to be cleaned until the distance between the cleaning strip 22 and the surface to be cleaned is the largest, the scraper 3 can scrape the cleaning strip 22 along the front surface of the cleaning strip 22 to remove foreign matter attached to the front side of the cleaning strip 22. The scraping process of the scraper 3 can not only remove foreign matter attached to the cleaning strip 22, and prevent foreign matter attached to the cleaning strip 22 from falling off when the cleaning head 10 is cleaning in the rear direction, causing secondary contamination to the cleaned ground, but also achieve preliminary cleaning of the cleaning strip 22 without affecting the normal operation of the cleaning head 10. Most importantly, the scraper 3 can also provide certain protection for the cleaning strip 22 in the rising state, preventing the cleaning strip 22 from being damaged by sharp objects in the environment or being damaged by other factors.

[0070] In the related art, the lifting and lowering movement of the cleaning scraper 22 is realized by the lifting drive 20. The lifting drive 20 can realize the linear up and down lifting movement of the cleaning scraper 22 relative to the cleaning member 21, and can also realize the rotational up and down lifting movement of the cleaning scraper 22 relative to the cleaning member 21. This embodiment does not limit its driving method and the lifting and lowering movement method of the cleaning scraper 22 relative to the cleaning member 21, as long as it can meet the normal lifting and lowering of the cleaning scraper 22.

[0071] Figure 4 for Figure 3 Schematic diagram of the assembly of the scraper 3 and the elastic member 5. Figure 2-Figure 4 The scraping member 3 can be connected to the housing 1 in a pivotal manner so as to be able to rotate relative to the housing 1 toward a side away from the cleaning strip 22 under the action of an external force.

[0072] Specifically, the scraper 3 can be movably connected to the shell 1 through the pivot shaft 4. The pivot shaft 4 is provided on the scraper 3 and the two ends of the pivot shaft 4 in the axial direction can extend into the shell 1 and be rotatably connected to the shell 1. Under the connecting action of the pivot shaft 4, the scraper 3 is rotatably connected to the shell 1. In this embodiment, an elastic member 5 is sleeved on the pivot shaft 4. Under the action of the elastic member 5, the end of the scraper 3 used for contacting the cleaning scraper 22 can maintain abutment with the cleaning scraper 22. Under the cooperation of the elastic member 5 and the cleaning scraper 22, the scraper 3 can rotate within a certain range relative to the shell 1 and cooperate with the front side surface of the cleaning scraper 22 to achieve covering of the front side surface of the cleaning scraper 22 and scraping off garbage attached to the front side surface of the cleaning scraper 22.

[0073] See also Figure 4The scraper 3 is provided with a scraping portion 31 and a contoured surface 32 on the side that contacts the cleaning strip 22. The scraping portion 31 is located at the free end of the scraper 3, i.e., the end of the scraper 3 facing away from the housing 1. As the cleaning strip 22 is raised and lowered relative to the cleaning head 10, the scraping portion 31 contacts the front surface of the cleaning strip 22, generating relative friction. The scraper 3 removes dirt adhering to the front side of the cleaning strip 22 by creating relative friction between the scraping portion 31 and the front surface of the cleaning strip 22.

[0074] In this embodiment, the scraping member 3 can abut against the cleaning strip 22 under the action of the elastic member 5 , that is, the scraping member 3 can abut against the cleaning strip 22 through the scraping portion 31 in contact with the front surface of the cleaning strip 22 .

[0075] It should be noted that when the cleaning strip 22 is raised or lowered relative to the cleaning head 10, the cleaning strip 22 will also move away from or closer to the scraping member 3, and in this process, the scraping portion 31 that always contacts its surface can push the scraping member 3 to rotate a certain angle.

[0076] Specifically, in response to the upward movement of the cleaning blade 22 , the scraping member 3 can be pushed by the cleaning blade 22 to deflect outward toward the front side of the cleaning blade 22 , and in this process, the elastic member 5 is driven to deform and store energy.

[0077] In this embodiment, the contoured surface 32 is disposed between the area of ​​the scraper 3 that is connected to the housing 1 and the scraping portion 31. When the scraper 3 covers the front surface of the cleaning strip 22, the contoured surface 32 allows the scraper 3 to engage with and maintain close contact with the front surface of the cleaning strip 22. When the cleaning strip 22 descends relative to the cleaning head 10, the contoured surface 32 of the scraper 3 separates from the front surface of the cleaning strip 22, and the scraping portion 31 abuts against the front surface of the cleaning strip 22.

[0078] Specifically, the contour of the profiling surface 32 matches the front surface of the cleaning strip 22. The profiling surface 32 can be in contact with at least a portion of the front surface of the cleaning strip 22 when the cleaning strip 22 is above the cleaning member 21.

[0079] When the front surface of the cleaning blade 22 includes a flat surface, the area corresponding to the contoured surface 32 is also a flat surface; when the front surface of the cleaning blade 22 includes a curved surface, the area corresponding to the contoured surface 32 is also a curved surface.

[0080] See also Figure 4 In this embodiment, the elastic member 5 comprises a torsion spring. One end of the torsion spring is fixedly connected to the scraping member 3, and the other end extends toward one side of the housing 1 to abut against the housing 1.

[0081] The torsion spring can provide a force to the scraping member 3 against the front surface of the cleaning blade 22 .

[0082] Considering that the cleaning strip 22 has a certain length, the length of the scraping member 3 should be no less than that of the cleaning strip 22 to ensure that the scraping member 3 can effectively cover and protect the cleaning strip 22. In order to ensure that the scraping member 3 can effectively scrape the cleaning strip 22 at different positions along its length, the elastic members 5 are provided in at least two numbers and are spaced apart.

[0083] See also Figure 2 Along the length direction of the scraper 3 or the housing 1 , there are three elastic members 5 , which are arranged at intervals at both ends and the middle of the scraper 3 .

[0084] In order to better fix the three elastic members 5, in some embodiments, the scraping member 3 can be pivotally connected to the housing 1 through a longer pivot shaft 4, and the three elastic members 5 are all sleeved on the pivot shaft 4, see Figure 2 .

[0085] There are three pivot shafts 4 , which are arranged at intervals along the length direction of the scraping member 3 . The three elastic members 5 are provided in a one-to-one correspondence with the three pivot shafts 4 .

[0086] It should be noted that Figure 2 and Figure 4 The elastic member 5 shown is a torsion spring. The shape of the torsion spring is for illustration only and does not limit the actual shape and installation position of the torsion spring. In actual arrangement, the shape of the torsion spring can be adaptively adjusted, and the number of torsion springs can be adaptively increased or decreased according to the specifications of the torsion spring.

[0087] The following combination Figure 5-Figure 7 , the cooperation manner between the scraping member 3 and the cleaning strip 22 in the cleaning head 10 provided in the embodiment of the present application is specifically described.

[0088] Figure 5 for Figure 3 The scraping member 3 and the cleaning strip 22 are partially assembled in the first state. Figure 6 for Figure 3 The scraping member 3 and the cleaning strip 22 are shown in another partial assembly diagram in the second state. Figure 7 for Figure 3 The scraping member 3 and the cleaning strip 22 are shown in another partial assembly diagram in the third state.

[0089] See also Figure 5 , at this time, the cleaning strip 22 is lowered relative to the cleaning member 21 until it contacts the surface to be cleaned. Figure 5Taking the angle shown as an example, at this time, the cleaning strip 22 extends downward relative to the scraping member 3, and the scraping portion 31 of the scraping member 3 can move toward the direction close to the position of the cleaning strip 22 under the elastic force of the elastic member 5, which is manifested as the scraping member 3 rotating as a whole at a certain angle to ensure that the scraping portion 31 of the scraping member 3 can always be against the front side surface of the cleaning strip 22. At this time, the contoured surface 32 of the scraping member 3 is separated from the cleaning strip 22, and the scraping portion 31 at the lower end of the scraping member 3 is against the front side surface of the cleaning strip 22 near the top surface, thereby forming a closed space above the cleaning strip 22, which helps to prevent foreign matter from directly contacting the top surface of the cleaning strip 22, thereby effectively improving the cleanliness of the space above the cleaning strip 22.

[0090] See also Figure 6 When the cleaning strip 22 rises relative to the cleaning member 21 to the maximum distance from the surface to be cleaned, Figure 6 Taking the angle shown as an example, the scraper 3 is subjected to the driving force provided by the cleaning bar 22 as it gradually rises. Under the action of this driving force, the scraper 3 overcomes the elastic force of the elastic member 5 and rotates a certain angle away from the cleaning bar 22. During this process, the scraping portion 31 of the scraper 3 maintains contact with the front surface of the cleaning bar 22 under the elastic force of the elastic member 5. As the cleaning bar 22 gradually rises to the set position, the contoured surface 32 of the scraper 3 conforms to the front surface of the cleaning bar 22 at the set position. At this point, the scraper 3 completely covers the front surface of the cleaning bar 22. During this process, the scraping portion 31, which maintains contact with the front surface of the cleaning bar 22, scrapes away foreign matter adhering to the surface of the cleaning bar 22. The scraped foreign matter falls to the ground and is removed by the cleaning head 10 as it moves forward.

[0091] When the cleaning strip 22 is extended outward relative to the cleaning head 10 again, as the cleaning strip 22 is extended, the abutment force of the cleaning strip 22 on the scraping member 3 is reduced. At this time, the scraping member 3 can be deflected toward the side close to the cleaning strip 22 under the elastic force of the elastic member 5, and the space above the cleaning strip 22 can be closed and protected again.

[0092] It should be noted that when the cleaning strip 22 and the scraping member 3 are Figure 6 In the illustrated state, the scraping member 3 covers at least a portion of the front surface of the cleaning strip 22 and is in contact with at least a portion of the front surface of the cleaning strip 22. The cleaning strip 22 can be accommodated within the scraping member 3. In this state, the lower end surface of the scraping member 3 can be flush with the lower end surface of the cleaning strip 22, or it can slightly protrude relative to the lower end surface of the cleaning strip 22. This is not limited in this embodiment, as long as it does not affect the normal operation of the scraping member 3 and the cleaning strip 22.

[0093] Of course, in some cases, there is a possibility that the foreign matter attached to the cleaning strip 22 is firmly bonded to the cleaning strip 22 and cannot be scraped off by the scraping portion 31. Figure 7 . Since the foreign matter attached to the front surface of the cleaning scraper 22 has a certain size, the scraper 3 can overcome the elastic force of the elastic member 5 and deflect a certain angle relative to the cleaning scraper 22 under the drive of the external force provided by the cleaning scraper 22 to prevent the scraper 3 from blocking the normal retraction of the cleaning scraper 22, thereby avoiding the possibility of the cleaning scraper 22 getting stuck during the retraction process. At this time, the elastic member 5 can produce greater elastic deformation driven by the scraper 3 and accumulate more elastic potential energy. This elastic potential energy can be released when the cleaning scraper 22 is extended relative to the cleaning head 10, and act on the scraper 3, so that the scraping portion 31 of the scraper 3 remains in contact with the front surface of the cleaning scraper 22.

[0094] That is to say, when the cleaning strip 22 is extended relative to the cleaning head 10, the scraping member 3 can contact and maintain abutment with the front side surface of the cleaning strip 22; when the cleaning strip 22 is retracted relative to the cleaning head 10, the scraping member 3 can cover at least part of the surface of the front side of the cleaning strip 22 and contact at least part of the surface of the front side of the cleaning strip 22, or deflect to a certain angle under the action of foreign matter to avoid getting stuck.

[0095] In other similar embodiments, the scraper 3 may also be connected to the housing 1 in other ways.

[0096] See also Figures 8-10 , Figure 8 This is a schematic cross-sectional view of a cleaning head 10 according to another embodiment of the present application. Figure 9 Figure 8 The scraping member 3 and the cleaning strip 22 are partially assembled in the first state. Figure 10 for Figure 8 The scraping member 3 and the cleaning strip 22 are shown in another partial assembly diagram in the second state.

[0097] In this embodiment, the cleaning head 10 further includes a lifting member 6 that is transmission-connected to the scraping member 3 . The lifting member 6 is configured to drive the scraping member 3 to move up and down relative to the housing 1 to accommodate or release the cleaning strip 22 .

[0098] The structures of the scraping member 3 and the cleaning strip 22 can be referred to above. At this time, a space for accommodating the lifting member 6 is formed in the housing 1. The scraping member 3 can be connected to the housing 1 through the lifting member 6 and can move up and down relative to the housing 1.

[0099] Driven by the lifting member 6, the scraping member 3 can generate a certain displacement relative to the cleaning strip 22, and through this position, it can cover and protect the front surface of the cleaning strip 22. Correspondingly, the scraping member 3 can also receive and release the cleaning strip 22 through its lifting action.

[0100] In some embodiments, the lifting member 6 can be a drive mechanism that directly drives the scraper bar to move up and down, such as a linear drive motor (cooperating with the cleaning scraper bar 22 that moves up and down), a rotary drive motor (cooperating with the cleaning scraper bar 22 that rotates and moves up and down), etc. Of course, the lifting member 6 can also be a passively driven structure, for example, a passively driven structure driven by the cleaning scraper bar 22.

[0101] Specifically, the lifting member 6 is in transmission connection with the cleaning blade 22. When the cleaning blade 22 is lifted or lowered, the lifting member 6 can respond to the lifting movement of the cleaning blade 22 and drive the scraping member 3 to move synchronously in the opposite direction relative to the cleaning blade 22.

[0102] See also Figure 8 The lifting member 6 includes a gear 61 and a driven rack 62 that mesh with each other, wherein the gear 61 is located between the cleaning strip 22 and the scraping member 3 and meshes with the cleaning strip 22; in addition, the driven rack 62 fixedly connected to the scraping member 3 also meshes with the gear 61.

[0103] Specifically, the cleaning strip 22 is also provided with an engagement member for engaging with the gear 61. When the cleaning strip 22 is in motion, the gear 61 can be driven to rotate by the engagement member. At this time, the driven rack 62 connected to the gear 61 generates an opposite motion to the cleaning strip 22 and drives the scraping member 3 to move synchronously.

[0104] See also Figure 9 When the cleaning strip 22 is lowered relative to the cleaning member 21 or the cleaning head 10 to contact the surface to be cleaned, Figure 9 Taking the angle shown as an example, the cleaning strip 22 extends downward relative to the scraping member 3, and the scraping member 3 can move toward the side away from the cleaning strip 22 under the drive of the lifting member 6. At this time, the distance between the scraping member 3 and the cleaning strip 22 is large. Figure 5 Taking the position shown as an example, at this time, the contoured surface 32 of the scraping member 3 is separated from the cleaning strip 22 , and the scraping portion 31 at the lower end of the scraping member 3 is separated from the front surface of the cleaning strip 22 .

[0105] See also Figure 10 When the cleaning strip 22 rises relative to the cleaning member 21 or the cleaning head 10 to the maximum distance from the surface to be cleaned, Figure 10Taking the angle shown as an example, the scraper 3 can move toward the side of the cleaning bar 22 as the cleaning bar 22 gradually retracts. During this process, the scraper portion 31 scrapes the surface of the cleaning bar 22 to remove foreign matter attached to it, until the contoured surface 32 of the scraper 3 is in contact with the front surface of the cleaning bar 22. At this point, the scraper 3 completely covers the front surface of the cleaning bar 22, and during this process, the scraper portion 31 scrapes away foreign matter attached to the surface of the cleaning bar 22. The scraped foreign matter falls to the ground and is removed by the cleaning head 10 as it moves forward.

[0106] When the cleaning strip 22 descends again relative to the cleaning head 10, as the cleaning strip 22 extends, the abutment force of the cleaning strip 22 on the scraping member 3 decreases, and the scraping member 3 can be deflected toward the side close to the cleaning strip 22 under the elastic force of the elastic member 5, and the space above the cleaning strip 22 is closed and protected again.

[0107] It is understood that the scraping member 3 provided in the embodiment of the present application can provide a certain degree of coverage and protection for the cleaning strip 22 by covering at least a portion of the front surface of the cleaning strip 22, and can help remove foreign matter attached to the surface of the cleaning strip 22, thereby preventing secondary contamination of the cleaning strip 22 during use. For users, the cleaning head 10 with the above-mentioned scraping member 3 can effectively protect the cleaning strip 22 and ultimately improve the user experience of the cleaning head 10, while also improving the user experience of the cleaning device 100 and cleaning system 1000 equipped with the cleaning head 10.

[0108] Based on the same inventive concept, an embodiment of the present application further provides a cleaning device 100 , which includes the above-mentioned cleaning head 10 .

[0109] Based on the same inventive concept, the embodiment of the present application further provides a cleaning system 1000 . The cleaning system 1000 includes the cleaning device 100 described above, and also includes a cleaning base station 200 for cooperating with the cleaning device 100 .

[0110] See also Figure 11 , Figure 11 This is a schematic diagram of the structure of the cleaning system 1000 provided in an embodiment of the present application. The cleaning base station 200 is used to park the cleaning equipment 100.

[0111] In some embodiments, the cleaning base station 200 also has a drying function. The cleaning base station 200 is at least configured to dry the cleaning head 10 of the cleaning device 100 .

[0112] At this time, the cleaning base station 200 can dry the cleaning head 10 parked on the cleaning base station 200 by generating a hot air flow.

[0113] In some embodiments, the cleaning base station 200 includes a base and a drying element 230, wherein the base is provided with a parking cavity 220 and an air outlet 210. The parking cavity 220 is used to park the cleaning head 10 of the cleaning device 100, and the air outlet 210 is located in front of the parking cavity 220 and is connected to the parking cavity 220. The drying element 230 is confined within the base and is in airflow communication with the parking cavity 220 through the air outlet 210. When the drying element 230 is in operation, the high-temperature airflow carrying a certain amount of heat can flow into the parking cavity 220 through the air outlet 210.

[0114] When the cleaning head 10 is placed in the parking chamber 220, the airflow can directly act on the cleaning head 10 to achieve a drying process for the cleaning head 10.

[0115] See also Figure 12 , Figure 12 for Figure 11 Schematic diagram of the cooperation between the cleaning head 10 and the cleaning base station 200 in the drying state.

[0116] When the cleaning device 100 is parked in the parking chamber 220, the scraping member 3 is located on the side of the cleaning bar 22 facing the air outlet 210. When the drying element 230 is activated and dries the cleaning head 10 placed in the parking chamber 220, a high-temperature airflow flows into the parking chamber 220 through the air outlet 210. Because the scraping member 3 is located on the side of the cleaning bar 22 facing the air outlet 210, it effectively blocks the high-temperature airflow from directly contacting and acting on the cleaning bar 22, thereby protecting the cleaning bar 22 from direct effects of the high-temperature airflow, reducing the possibility of damage to the cleaning bar 22 due to high-temperature aging, and helping to extend its service life.

[0117] See also Figure 12 When the cleaning head 10 is placed on the cleaning base station 200 for drying, the hot air flow is released through the air outlet 210 on the cleaning base station 200 and flows toward the location of the cleaning blade 22. At this time, under the coverage and protection of the scraping element 3, the hot air flow cannot directly blow against the cleaning blade 22. This can effectively reduce the impact of the hot air flow on the cleaning blade 22, prevent the cleaning blade 22 from rapid aging and deformation, and help extend the service life of the cleaning blade 22.

[0118] Of course, when the cleaning strip 22 extends downward relative to the cleaning head 10, making it difficult for the scraping member 3 to properly cover and shield the cleaning strip 22, the portion of the cleaning strip 22 exposed relative to the scraping member 3 will also be affected by the high-temperature airflow, causing the aging rate to accelerate. In order to reduce the possibility of the above situation and better protect the cleaning strip 22, in some embodiments, the cleaning system 1000 also includes a controller 300, and the cleaning device 100 includes a lifting drive member 20 that is transmission-connected to the cleaning strip 22. The controller 300 is electrically connected to the drying element 230 and the lifting drive member 20. Please refer to Figure 13 , Figure 13 This is a schematic diagram of the connection between the controller 300, the drying element 230, and the lifting drive member 20 in the cleaning system 1000 provided in an embodiment of the present application.

[0119] When the drying element 230 is activated, the controller 300 is configured to control the lifting drive 20 to drive the cleaning strip 22 to rise relative to the cleaning element 21 and be accommodated inside the scraping element 3 in response to the activation of the drying element 230 .

[0120] At this time, it can be ensured that the cleaning scraper 22 can rise relative to the cleaning member 21 and be accommodated inside the scraping member 3 when the drying element 230 is started, so that the scraping member 3 can effectively protect the cleaning scraper 22, avoid high-temperature airflow directly acting on the cleaning scraper 22, and help extend the service life of the cleaning scraper 22.

[0121] The above description of the various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced with each other and will not be repeated herein for the sake of brevity.

[0122] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
