Technical Field

[0001] This application belongs to the field of cleaning equipment, and more specifically, relates to a cleaning head, cleaning equipment and cleaning system. Background Technology

[0002] With the iterative updates and development of technology, cleaning equipment has also diversified. Taking floor cleaning equipment as an example, in addition to using roller brushes to clean the floor, the cleaning heads of these devices are also equipped with cleaning squeegees for scraping the floor, better handling liquid stains and water stains. However, in related technologies, cleaning squeegees tend to accumulate a certain amount of debris after prolonged use, causing secondary pollution during the cleaning process and affecting the user experience to some extent. Furthermore, when using hot air to dry the cleaning equipment, the cleaning squeegees are affected by the high temperature, accelerating aging and reducing their lifespan. This necessitates frequent squeegee replacements, adding a burden to daily use and further diminishing the user experience. Summary of the Invention

[0003] This application aims to improve the user experience of cleaning squeegees, and at least to some extent improve the user experience of cleaning heads, cleaning equipment, and cleaning systems with such cleaning squeegees.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, a cleaning head is provided, the cleaning head being used at least in a cleaning device, the cleaning head including a housing, a cleaning unit, and a scraping member, the cleaning unit including a cleaning element and a cleaning scraper, the cleaning element being rotatably disposed within the housing, the cleaning scraper being disposed on the front side of the cleaning element and capable of vertical movement relative to the cleaning element; the scraping member being disposed on the side of the cleaning scraper facing away from the cleaning element; wherein, in response to the vertical movement of the cleaning scraper, the scraping member and the cleaning scraper generate relative movement to cover at least a portion of the surface on the front side of the cleaning scraper.

[0006] In one possible implementation, the squeegee is pivotally connected to the housing so that it can rotate relative to the housing toward a side away from the cleaning squeegee under the action of an external force.

[0007] In one feasible implementation, the scraping element is movably connected to the housing via a pivot shaft, and an elastic element is sleeved on the pivot shaft.

[0008] In one feasible implementation, the elastic element includes a torsion spring, the two ends of which are fixedly connected to the housing and the scraping element, respectively.

[0009] In one possible implementation, the number of pivot shafts is at least two and they are spaced apart along the length of the housing.

[0010] In one possible implementation, as the cleaning squeegee rises relative to the cleaning member, the area covered by the squeegee member on the front side of the cleaning squeegee gradually increases;

[0011] In response to the upward movement of the cleaning squeegee, the squeegee can be in contact with at least a portion of the front surface of the cleaning squeegee and housed inside the squeegee, or it can deflect outward toward the front side of the cleaning squeegee and cause the elastic element to deform and store energy.

[0012] In one possible implementation, the cleaning head further includes a lifting member drivenly connected to the scraper, the lifting member being configured to drive the scraper to move up and down relative to the housing to receive or release the cleaning squeegee.

[0013] In one feasible implementation, the lifting member is drivenly connected to the cleaning squeegee, and in response to the lifting movement of the cleaning squeegee, the squeegee can move synchronously in the opposite direction to the cleaning squeegee.

[0014] In one feasible implementation, the lifting member includes a meshing gear and a driven rack, the gear being meshed with the cleaning scraper, and the driven rack being fixedly connected to the scraper.

[0015] In one feasible implementation, the scraper is provided with a scraping portion, and the scraper generates relative friction with the front surface of the cleaning squeegee at least through the scraping portion.

[0016] In one possible implementation, the scraping portion is located at the end of the scraping member facing away from the housing.

[0017] In one possible implementation, the squeegee is provided with a contoured surface that is designed to abut at least a portion of the surface of the front side of the cleaning squeegee as the cleaning squeegee rises relative to the cleaning head.

[0018] In a second aspect, a cleaning device is provided, comprising the cleaning head described in any of the preceding claims.

[0019] In a third aspect, a cleaning system is provided, including a cleaning base station and the cleaning equipment described above, wherein the cleaning base station is used to park the cleaning equipment.

[0020] In one feasible implementation, the cleaning base station is at least configured to dry the cleaning head of the cleaning device, the cleaning base station comprising:

[0021] The base has a storage cavity and an air outlet. The storage cavity is used to store the cleaning head of the cleaning device, and the air outlet is located in front of the storage cavity and is connected to the storage cavity.

[0022] The drying element is located within the substrate and is in airflow communication with the parking chamber through the air outlet;

[0023] When the cleaning equipment is placed in the parking cavity, the scraper is located on the side of the cleaning scraper facing the air outlet.

[0027] Compared with the prior art, this application includes at least the following beneficial effects:

[0028] The cleaning head provided in this application embodiment can cover and protect at least a portion of the front surface of the cleaning squeegee through a scraping member located on the side of the cleaning squeegee facing away from the cleaning component. Simultaneously, as the cleaning squeegee moves up and down relative to the cleaning component, the scraping member can move relative to the cleaning squeegee and adjust the range of its coverage on the cleaning squeegee surface, effectively protecting the cleaning squeegee without affecting its normal use. For example, in the drying state, the scraping member can protect the cleaning squeegee by covering and shielding its front surface, preventing high-temperature airflow from directly impacting the squeegee and helping to extend its service life. When the cleaning squeegee descends relative to the cleaning component and gradually approaches the surface to be cleaned, the scraping member can seal the upper space of the cleaning squeegee to prevent debris from entering the space above it. When the cleaning squeegee rises relative to the cleaning component and gradually moves away from the surface to be cleaned, the scraping member can remove debris adhering to the front surface of the cleaning squeegee by scraping its surface, thus preventing secondary contamination during use. For users, the aforementioned cleaning head can help extend the lifespan of the cleaning squeegee by covering and protecting it with a swiping component, and reduce the possibility of secondary contamination during cleaning by swiping the surface of the cleaning squeegee, ultimately improving the user experience.

[0029] The cleaning equipment and cleaning system provided in this application both include the above-mentioned cleaning head. Therefore, the beneficial effects of the cleaning equipment and cleaning system including any one or more of the above-mentioned cleaning heads will not be repeated here. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0054] This application provides a cleaning head 10, a cleaning device 100, and a cleaning system 1000, wherein the cleaning head 10 is used at least in 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 used to park the cleaning device 100 at least. When the cleaning device 100 is in operation, it can clean the surface to be cleaned by direct contact.

[0056] For example, the surface to be cleaned can be a floor, in which case the cleaning equipment 100 can be a floor scrubber, or a sweeping and mopping robot, a mopping robot, a steam mop, or other floor cleaning tools used to clean the floor. When the surface to be cleaned is a wall or a window, the cleaning equipment 100 can be a window cleaning machine, etc.

[0057] Taking a floor scrubber as an example, the cleaning device 100 is suitable for cleaning hard floors and can perform dust collection, mopping, and washing functions. The cleaning device 100 includes a connected cleaning head 10 and a body. The cleaning head 10 is used to directly contact the surface to be cleaned, and the body is for the user to hold. When the cleaning device 100 is placed on the cleaning base station 200, the cleaning head 10 directly contacts the base station, and the cleaning base station 200 can perform cleaning on the cleaning device 100.

[0058] The cleaning head 10 has a front side and a rear side when in use. The bottom surface of the cleaning head 10, which is used to directly contact the surface to be cleaned, is provided with a cleaning element 21 (such as a cleaning brush). The cleaning element 21 is provided with a cleaning scraper 22 (i.e., the cleaning scraper 22 is a front scraper) facing the outside. The cleaning scraper 22 can move up and down relative to the cleaning element 21, so as to rise or fall relative to the cleaning element 21. When the cleaning head 10 moves forward and cleans the surface to be cleaned, the cleaning component 21 can directly contact the surface to be cleaned and clean it. At this time, the cleaning squeegee 22 rises relative to the cleaning component 21 to create a larger clearance between it and the surface to be cleaned, thus avoiding direct contact between the cleaning squeegee 22 and the surface to be cleaned. This avoids the problem of jamming caused by the cleaning squeegee 22 directly contacting large debris on the ground, allowing the cleaning head 10 to move smoothly forward. When the cleaning head 10 moves backward and cleans the surface to be cleaned, the cleaning squeegee 22 descends relative to the cleaning component 21 and directly contacts the surface to be cleaned to scrape away dirt and water stains. At this time, the cleaning squeegee 22 can effectively scrape away dirt and water stains attached to the surface to be cleaned, thereby improving the cleaning efficiency and cleaning effect of the cleaning head 10.

[0059] During the repeated forward and backward cleaning process of the cleaning head 10, some debris will adhere to the outer surface of the cleaning blade 22 facing forward. If the cleaning blade 22 rises as the cleaning head 10 moves forward, the debris will enter the housing of the cleaning head 10, thus contaminating the cleaning blade 22. Furthermore, when the cleaning blade 22 extends again as the cleaning head 10 moves backward, some debris will fall off, causing secondary contamination of the surface to be cleaned. In addition, the debris adhering to the front surface of the cleaning blade 22 can also contaminate the user's furniture and walls during use, reducing the user experience to some extent.

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

[0061] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the cleaning head 10 provided in the embodiments of this application. Figure 2 This is a partial structural schematic diagram of the cleaning head 10 provided in the embodiments of this application.

[0062] The cleaning head 10 provided in this embodiment includes a housing 1, a cleaning unit 2, and a scraping member 3. The cleaning unit 2 includes the cleaning member 21 and the cleaning scraper 22 described above. The cleaning member 21 is rotatably disposed within the housing 1 for cleaning the surface to be cleaned. The cleaning scraper 22 is disposed on the front side of the cleaning member 21 and can move up and down relative to the cleaning member 21 to scrape and clean the surface to be cleaned when it descends relative to the cleaning member 21 to contact the surface to be cleaned. The scraping member 3 is disposed on the side of the cleaning scraper 22 facing away from the cleaning member 21. When the cleaning scraper 22 moves up and down relative to the cleaning member 21, in response to the movement of the cleaning scraper 22, the scraping member 3 moves relative to the cleaning scraper 22 and covers at least a portion of the surface on the front side of the cleaning scraper 22.

[0063] Please see Figure 1 and Figure 2 The scraper 3 is mounted on the housing 1 and is located in front of the cleaning squeegee 22. As the cleaning squeegee 22 moves up and down, the relative position between the scraper 3 and the cleaning squeegee 22 changes, and the area covered by the scraper 3 on the cleaning squeegee 22 gradually increases as the cleaning squeegee 22 rises.

[0064] At least a portion of the squeegee 3 is located on the lifting path of the cleaning squeegee 22. (See also...) Figure 3 , Figure 3for Figure 2 A cross-sectional structural schematic diagram of one embodiment. In response to the lifting and lowering movement of the cleaning squeegee 22, the squeegee 3 generates relative friction with the front surface of the cleaning squeegee 22 to receive or release the cleaning squeegee 22.

[0065] As the cleaning squeegee 22 rises relative to the cleaning member 21, the scraping member 3 scrapes the surface of the cleaning squeegee 22 by generating relative friction with its front surface, helping to remove dirt adhering to the front surface of the cleaning squeegee 22. When the cleaning squeegee 22 reaches its highest position, the scraping member 3 can then accommodate the cleaning squeegee 22. (See also...) Figure 3 At this point, the front surface of the cleaning squeegee 22 is completely covered by the squeegee 3, or is basically covered by the squeegee 3.

[0066] In other words, as the cleaning squeegee 22 rises relative to the cleaning member 21, the area covered by the squeegee 3 on the front side of the cleaning squeegee 22 gradually increases. In response to the upward movement of the cleaning squeegee 22, the squeegee 3 can come into contact with at least a portion of the surface on the front side of the cleaning squeegee 22 and be housed inside the squeegee 3.

[0067] As the cleaning squeegee 22 descends relative to the cleaning component 21, the scraping component 3 can maintain contact with the front surface of the cleaning squeegee 22 by rubbing against it, thus preventing external dirt from entering the area above the cleaning squeegee 22 through the gap between the cleaning squeegee 22 and the scraping component 3.

[0068] For example, when the cleaning squeegee 22 is in the working position, i.e., close to and in contact with the surface to be cleaned, the scraper 3 can contact the front surface of the cleaning squeegee 22 near the top or the top surface, and at least cover the top of the cleaning squeegee 22, thereby sealing off the space above the cleaning squeegee 22. At this time, when the cleaning head 10 is performing cleaning operations, the scraper 3 can act as a barrier to prevent external foreign objects from contacting and entering the space above the cleaning squeegee 22, thus ensuring the cleanliness of the space above the cleaning squeegee 22.

[0069] When the cleaning squeegee 22 moves away from the surface to be cleaned until the distance between them is at its maximum, the scraping element 3 can scrape the cleaning squeegee 22 along its front surface to remove foreign objects adhering to it. The scraping action of the scraping element 3 not only removes foreign objects from the cleaning squeegee 22, preventing them from falling off and causing secondary pollution to the cleaned floor when the cleaning head 10 moves backward, but also provides initial cleaning of the cleaning squeegee 22 without affecting the normal operation of the cleaning head 10. Most importantly, the scraping element 3 also provides some protection for the cleaning squeegee 22 when it is in the rising position, preventing it from being damaged by sharp objects in the environment or by other factors.

[0070] In related technologies, the lifting and lowering movement of the cleaning squeegee 22 is achieved by the lifting drive 20. The lifting drive 20 can realize the linear up-and-down movement of the cleaning squeegee 22 relative to the cleaning component 21, or it can realize the rotational up-and-down movement of the cleaning squeegee 22 relative to the cleaning component 21. This embodiment does not limit its driving method or the lifting and lowering movement of the cleaning squeegee 22 relative to the cleaning component 21, as long as the normal lifting and lowering of the cleaning squeegee 22 can be satisfied.

[0071] Figure 4 for Figure 3 A schematic diagram of the assembly of the scraping component 3 and the elastic component 5 is shown below. Please refer to [the diagram]. Figures 2-4 The scraper 3 can be pivotally connected to the housing 1 so that it can rotate relative to the housing 1 toward the side away from the cleaning scraper 22 under the action of external force.

[0072] Specifically, the scraper 3 can be movably connected to the housing 1 via a pivot shaft 4. The pivot shaft 4 passes through the scraper 3, and both ends of the pivot shaft 4 extend into the housing 1 and are rotatably connected to the housing 1. Under the connection of the pivot shaft 4, the scraper 3 is rotatably connected to the housing 1. In this embodiment, an elastic element 5 is sleeved on the pivot shaft 4. Under the action of the elastic element 5, the end of the scraper 3 that contacts the cleaning scraper 22 can maintain contact with the cleaning scraper 22. With the cooperation of the elastic element 5 and the cleaning scraper 22, the scraper 3 can rotate relative to the housing 1 within a certain range and cooperate with the front surface of the cleaning scraper 22 to cover the front surface of the cleaning scraper 22 and scrape off the debris attached to the front surface of the cleaning scraper 22.

[0073] Please see Figure 4The scraper 3 has a scraping part 31 and a contoured surface 32 on the side that contacts the cleaning squeegee 22. The scraping part 31 is located at the free end of the scraper 3, that is, the end of the scraper 3 facing away from the housing 1. During the raising and lowering of the cleaning squeegee 22 relative to the cleaning head 10, the scraping part 31 contacts the front surface of the cleaning squeegee 22 and generates relative friction. The scraper 3 can remove dirt adhering to the front side of the cleaning squeegee 22 by generating relative friction between the scraping part 31 and the front surface of the cleaning squeegee 22.

[0074] In this embodiment, the scraping member 3 can abut against the cleaning squeegee 22 under the action of the elastic member 5. That is, the scraping member 3 can abut against the cleaning squeegee 22 through the scraping part 31 that contacts the front surface of the cleaning squeegee 22.

[0075] It should be noted that when the cleaning squeegee 22 moves up and down relative to the cleaning head 10, the cleaning squeegee 22 will also move away from or closer to the scraping part 3. During this process, the scraping part 31, which is always in contact with its surface, will push the scraping part 3 to rotate at a certain angle.

[0076] Specifically, in response to the upward movement of the cleaning blade 22, the scraping member 3 can deflect outward toward the front side of the cleaning blade 22 under the push of the cleaning blade 22, and in this process, the elastic member 5 deforms and stores energy.

[0077] In this embodiment, the contoured surface 32 is disposed between the area of ​​the scraper 3 for connection with the housing 1 and the scraping portion 31. When the scraper 3 covers the front surface of the cleaning squeegee 22, the scraper 3 can engage with and remain in close contact with the front surface of the cleaning squeegee 22 through the contoured surface 32; when the cleaning squeegee 22 descends relative to the cleaning head 10, the contoured surface 32 of the scraper 3 separates from the front surface of the cleaning squeegee 22, and the scraping portion 31 abuts against the front surface of the cleaning squeegee 22.

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

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

[0080] Please see Figure 4 In this embodiment, the elastic element 5 includes a torsion spring. One end of the torsion spring is fixedly connected to the scraping element 3, and the other end extends toward the housing 1 to abut against the housing 1.

[0081] The torsion spring can provide a force to the scraper 3 that resists the front surface of the cleaning scraper 22.

[0082] Considering that the cleaning squeegee 22 has a certain length, the length of the scraping member 3 should be no less than the length of the cleaning squeegee 22 to ensure that the scraping member 3 can provide good coverage and protection for the cleaning squeegee 22. In order to enable the scraping member 3 to provide good scraping effect on the cleaning squeegee 22 at different positions along its length, at least two elastic members 5 are provided and spaced apart.

[0083] Please see Figure 2 Along the length of the scraper 3 or the housing 1, there are three elastic elements 5, which are spaced apart at both ends and the middle of the scraper 3.

[0084] To better secure the three elastic elements 5, in some embodiments, the scraping element 3 can be pivotally connected to the housing 1 via a relatively long pivot shaft 4, and all three elastic elements 5 are sleeved on the pivot shaft 4. Please refer to [link to relevant documentation]. Figure 2 .

[0085] There are three pivot shafts 4, which are arranged at intervals along the length of the scraping member 3. The three elastic members 5 are set 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 element 5 shown is a torsion spring. The shape of this torsion spring is for illustrative purposes only and is not intended to limit its actual shape or installation position. In actual installation, the shape of the torsion spring can be adjusted, and the number of torsion springs can be increased or decreased according to their specifications.

[0087] The following is combined Figures 5-7 The following is a detailed description of the interaction between the scraper 3 and the cleaning blade 22 in the cleaning head 10 provided in this embodiment.

[0088] Figure 5 for Figure 3 The diagram shown is a partial assembly diagram of the scraper 3 and the cleaning scraper 22 in the first state. Figure 6 for Figure 3 The diagram shown illustrates another part of the assembly of the scraper 3 and the cleaning scraper 22 in the second state. Figure 7 for Figure 3 The diagram shows another partial assembly of the scraper 3 and the cleaning scraper 22 in the third state.

[0089] Please see Figure 5 At this point, the cleaning scraper 22 descends relative to the cleaning component 21 until it contacts the surface to be cleaned. Figure 5Taking the angle shown as an example, at this time, the cleaning squeegee 22 extends downward relative to the scraper 3. The scraping part 31 of the scraper 3 can move towards the position of the cleaning squeegee 22 under the elastic force of the elastic member 5. This means that the scraper 3 rotates at a certain angle to ensure that the scraping part 31 of the scraper 3 can always abut against the front surface of the cleaning squeegee 22. At this time, the contour surface 32 of the scraper 3 is separated from the cleaning squeegee 22, and the scraping part 31 at the lower end of the scraper 3 abuts against the front surface of the cleaning squeegee 22 near the top surface. This forms a closed space above the cleaning squeegee 22, which helps to prevent foreign objects from directly contacting the top surface of the cleaning squeegee 22, thereby effectively improving the cleanliness of the space above the cleaning squeegee 22.

[0090] Please see Figure 6 When the cleaning squeegee 22 rises relative to the cleaning component 21 to its maximum distance from the surface to be cleaned, it... Figure 6 Taking the angle shown as an example, the scraper 3 can be driven by the cleaning squeegee 22 as it gradually rises. Under the action of this driving force, the scraper 3 can overcome the elastic force of the elastic member 5 and rotate a certain angle away from the cleaning squeegee 22. During this process, the scraping part 31 of the scraper 3 can always remain in contact with the front surface of the cleaning squeegee 22 under the action of the elastic force of the elastic member 5. As the cleaning squeegee 22 gradually rises to the set position, the contoured surface 32 of the scraper 3 can fit against the front surface of the cleaning squeegee 22 located at the set position. At this time, the scraper 3 completely covers the front surface of the cleaning squeegee 22, and in this process, the scraping part 31, which always remains in contact with the front surface of the cleaning squeegee 22, scrapes away the foreign matter attached to the surface of the cleaning squeegee 22. The scraped foreign matter can fall to the ground and be removed by the cleaning head 10 as it moves forward.

[0091] When the cleaning squeegee 22 extends outward relative to the cleaning head 10 again, as the cleaning squeegee 22 extends, the resistance force of the cleaning squeegee 22 against the scraping member 3 decreases. At this time, the scraping member 3 can be deflected towards the side closer to the cleaning squeegee 22 under the elastic force of the elastic member 5, and the space above the cleaning squeegee 22 can be closed and protected again.

[0092] It should be noted that when the cleaning scraper 22 and the scraper part 3 are... Figure 6 In the indicated state, the squeegee 3 covers at least a portion of the front surface of the cleaning squeegee 22 and is in contact with at least a portion of the front surface of the cleaning squeegee 22. The cleaning squeegee 22 can be housed inside the squeegee 3. In this state, the lower end face of the squeegee 3 can be on the same plane as the lower end face of the cleaning squeegee 22, or it can slightly protrude relative to the lower end face of the cleaning squeegee 22, as long as it does not affect the normal use of the squeegee 3 and the cleaning squeegee 22. This embodiment does not limit this.

[0093] Of course, in some cases, foreign matter adhering to the cleaning squeegee 22 may be firmly bonded to it and cannot be scraped off by the squeegee part 31. Please refer to [link / reference needed]. Figure 7 Because the foreign matter attached to the front surface of the cleaning squeegee 22 has a certain size, the scraping member 3, driven by the external force provided by the cleaning squeegee 22, can overcome the elastic force of the elastic member 5 and deflect at a certain angle relative to the cleaning squeegee 22 to prevent the scraping member 3 from obstructing the normal retraction of the cleaning squeegee 22, thereby avoiding the possibility of the cleaning squeegee 22 getting stuck during retraction. At this time, the elastic member 5 can generate greater elastic deformation under the action of the scraping member 3 and accumulate more elastic potential energy. This elastic potential energy can be released when the cleaning squeegee 22 extends relative to the cleaning head 10 and act on the scraping member 3, so that the scraping part 31 of the scraping member 3 keeps in contact with the front surface of the cleaning squeegee 22.

[0094] In other words, when the cleaning squeegee 22 extends relative to the cleaning head 10, the squeegee 3 can contact and remain in contact with the front surface of the cleaning squeegee 22; when the cleaning squeegee 22 retracts relative to the cleaning head 10, the squeegee 3 can cover at least a portion of the front surface of the cleaning squeegee 22 and contact at least a portion of the front surface of the cleaning squeegee 22, or deflect at a certain angle under the action of foreign objects to avoid getting stuck.

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

[0096] Please see Figures 8-10 , Figure 8 This is a cross-sectional view of the cleaning head 10 in another embodiment provided in this application. Figure 9 Figure 8 The diagram shown is a partial assembly diagram of the scraper 3 and the cleaning scraper 22 in the first state. Figure 10 for Figure 8 The diagram shows another part of the assembly of the scraper 3 and the cleaning scraper 22 in the second state.

[0097] In this embodiment, the cleaning head 10 also includes a lifting member 6 that is connected to the scraper 3 in a transmission manner. The lifting member 6 is configured to drive the scraper 3 to move up and down relative to the housing 1 to receive or release the cleaning scraper 22.

[0098] The structure of the scraper 3 and the cleaning blade 22 can be referred to the previous text. At this time, a space is formed inside the housing 1 to accommodate the aforementioned lifting member 6. The scraper 3 can be connected to the housing 1 via the lifting member 6 and can move up and down relative to the housing 1.

[0099] Driven by the lifting component 6, the scraping component 3 can be displaced relative to the cleaning squeegee 22, thereby covering and protecting the front surface of the cleaning squeegee 22. Correspondingly, the scraping component 3 can also receive and release the cleaning squeegee 22 through its lifting action.

[0100] In some embodiments, the lifting member 6 can be a drive mechanism that can directly drive the cleaning blade to perform lifting and lowering actions, such as a linear drive motor (cooperating with the vertically lifting cleaning blade 22), a rotary drive motor (cooperating with the rotating lifting cleaning blade 22), etc. Of course, the lifting member 6 can also be a passively driven structure, such as a passively driven structure driven by the cleaning blade 22.

[0101] Specifically, the lifting component 6 is connected to the cleaning squeegee 22 via a transmission. When the cleaning squeegee 22 is raised or lowered, the lifting component 6 can respond to the raising or lowering motion of the cleaning squeegee 22 and drive the scraping component 3 to move synchronously in the opposite direction relative to the cleaning squeegee 22.

[0102] Please see Figure 8 The lifting component 6 includes a gear 61 and a driven rack 62 that mesh with each other. The gear 61 is located between the cleaning scraper 22 and the scraper 3 and meshes with the cleaning scraper 22. In addition, the driven rack 62, which is fixedly connected to the scraper 3, also meshes with the gear 61.

[0103] Specifically, the cleaning scraper 22 is also provided with a meshing element for engaging with the gear 61. When the cleaning scraper 22 is in motion, it can drive the gear 61 to rotate through the meshing element. At this time, the driven rack 62 connected to the gear 61 produces an action opposite to that of the cleaning scraper 22 and drives the scraping element 3 to move synchronously.

[0104] Please see Figure 9 When the cleaning squeegee 22 descends relative to the cleaning component 21 or the cleaning head 10 until it contacts the surface to be cleaned, Figure 9 Taking the angle shown as an example, at this time, the cleaning squeegee 22 extends downward relative to the scraper 3, and the scraper 3 can move away from the cleaning squeegee 22 under the drive of the lifting member 6. At this time, the distance between the scraper 3 and the cleaning squeegee 22 is relatively large. Figure 5 Taking the position shown as an example, at this time, the contour surface 32 of the scraper 3 is separated from the cleaning scraper 22, and the scraping part 31 at the lower end of the scraper 3 is separated from the front surface of the cleaning scraper 22.

[0105] Please see Figure 10 When the cleaning squeegee 22 rises relative to the cleaning component 21 or the cleaning head 10 to the maximum distance between it and the surface to be cleaned, it... Figure 10Taking the angle shown as an example, the scraper 3 can move towards the side closer to the cleaning squeegee 22 as the cleaning squeegee 22 is gradually retracted. During this process, the scraping part 31 scrapes the surface of the cleaning squeegee 22 to remove foreign objects adhering to its surface until the contoured surface 32 of the scraper 3 is in contact with the front surface of the cleaning squeegee 22. At this point, the scraper 3 completely covers the front surface of the cleaning squeegee 22, and the scraping part 31 removes the foreign objects adhering to the surface of the cleaning squeegee 22. The scraped foreign objects can fall to the ground and be removed by the cleaning head 10 as it moves forward.

[0106] When the cleaning squeegee 22 descends again relative to the cleaning head 10, as the cleaning squeegee 22 extends, the resistance force of the cleaning squeegee 22 against the scraping member 3 decreases. The scraping member 3 can be deflected towards the side closer to the cleaning squeegee 22 under the elastic force of the elastic member 5, and the space above the cleaning squeegee 22 is sealed and protected again.

[0107] It is understood that the squeegee 3 provided in this application embodiment can provide a certain degree of coverage and protection for the cleaning squeegee 22 by covering at least a portion of the front surface of the cleaning squeegee 22, and can help remove foreign matter attached to the surface of the cleaning squeegee 22, so as to avoid secondary pollution of the cleaning squeegee 22 during use. For users, the cleaning head 10 with the above-mentioned squeegee 3 can effectively protect the cleaning squeegee 22 and ultimately improve the user experience of the cleaning head 10, and can also improve the user experience of the cleaning device 100 and the cleaning system 1000 with the cleaning head 10.

[0108] Based on the same inventive concept, this application also provides a cleaning device 100, which includes the cleaning head 10 described above.

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

[0110] Please see Figure 11 , Figure 11 This is a schematic diagram of the structure of the cleaning system 1000 provided in an embodiment of this 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, and 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 placed on the cleaning base station 200 by generating a hot airflow.

[0113] In some embodiments, the cleaning base station 200 includes a substrate and a drying element 230. The substrate 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. The air outlet 210 is located in front of the parking cavity 220 and communicates with the parking cavity 220. The drying element 230 is confined within the substrate and is in airflow communication with the parking cavity 220 through the air outlet 210. The high-temperature airflow carrying a certain amount of heat generated when the drying element 230 is working can flow to the parking cavity 220 through the air outlet 210.

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

[0115] Please see Figure 12 , Figure 12 for Figure 11 A schematic diagram showing the interaction between the cleaning head 10 and the cleaning base station 200 in the drying state.

[0116] When the cleaning device 100 is placed in the parking chamber 220, the scraper 3 is located on the side of the cleaning scraper 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, the high-temperature airflow flows into the parking chamber 220 through the air outlet 210. Since the scraper 3 is located on the side of the cleaning scraper 22 facing the air outlet 210, it can effectively prevent the high-temperature airflow from directly contacting and acting on the cleaning scraper 22, thereby protecting the cleaning scraper 22 from the direct action of the high-temperature airflow, helping to reduce the possibility of damage to the cleaning scraper 22 due to high-temperature aging, and helping to extend its service life.

[0117] Please see Figure 12 When the cleaning head 10 is placed on the cleaning base station 200 for drying, the hot airflow is released through the air outlet 210 on the cleaning base station 200 and flows to the location of the cleaning squeegee 22. At this time, under the coverage and protection of the squeegee 3, the hot airflow cannot blow directly onto the cleaning squeegee 22, thus effectively improving the impact of the hot airflow on the cleaning squeegee 22, preventing the cleaning squeegee 22 from aging and deforming rapidly, and helping to extend the service life of the cleaning squeegee 22.

[0118] Of course, when the cleaning squeegee 22 extends downward relative to the cleaning head 10, making it difficult for the scraper 3 to effectively cover and shield the cleaning squeegee 22, the exposed portion of the cleaning squeegee 22 relative to the scraper 3 will also experience accelerated aging due to the influence of the high-temperature airflow. To reduce the likelihood of this happening and better protect the cleaning squeegee 22, in some embodiments, the cleaning system 1000 further includes a controller 300. The cleaning device 100 includes a lifting drive 20 that is driveably connected to the cleaning squeegee 22. The controller 300 is electrically connected to the drying element 230 and the lifting drive 20. Please refer to [link to relevant documentation]. Figure 13 , Figure 13 This is a schematic diagram showing the connection between the controller 300, the drying element 230, and the lifting drive component 20 in the cleaning system 1000 provided in this embodiment of the application.

[0119] When the drying element 230 is started, the controller 300 is configured to control the lifting drive 20 to drive the cleaning scraper 22 to rise relative to the cleaning element 21 and be housed inside the scraper 3 in response to the start of the drying element 230.

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

[0121] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

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