[0015] In one feasible implementation, the drive member is located on one side of the limiting housing and is connected to both the limiting housing and the mounting base, so as to provide a driving force to the mounting base away from the limiting housing.

[0016] In one possible implementation, the mounting base includes a detachably connected guide portion and a fastening bolt, the guide portion passing through the guide limiting hole and connected to the fastening bolt.

[0024] Compared with the prior art, this application includes at least the following beneficial effects:

[0025] The cleaning head provided in this application includes a cleaning component and a floating water distribution unit. The water distribution component in the floating water distribution unit can always remain in contact with the cleaning component under the drive of the driving component. This ensures that during the rotation of the cleaning component, a continuous pressing force is always applied to the cleaning component by contact with its surface. This ensures that the cleaning liquid on the surface of the cleaning component can fully wet the surface of the cleaning component, thereby achieving a better water distribution effect. When the cleaning liquid has a certain temperature, the temperature of the surface of the cleaning component can be raised uniformly to further improve its cleaning effect. Most importantly, the water distribution component can adapt to the cleaning component in different states under the drive of the driving component, ensuring that a good water distribution effect can still be maintained even when the cleaning component has a certain degree of wear. At the same time, the water distribution component can reduce the friction between itself and the cleaning component by rotating relative to the cleaning component, thereby reducing wear on the cleaning component and helping to extend the service life of the cleaning component. It also ensures that the cleaning component always has a good cleaning effect during use, so as to provide users with a better user experience.

[0026] The cleaning equipment and cleaning system provided in this application include the cleaning head for the cleaning equipment described above. 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

[0050] Figure 1 This is a schematic diagram of the structure of the cleaning system 1000 provided in an embodiment of this application.

[0051] This application provides a cleaning head 10, a cleaning device 100, and a cleaning system 1000, wherein the cleaning device 100 has the aforementioned cleaning head 10.

[0052] Please see Figure 1 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 contact the work surface to be cleaned through the cleaning head 10 and perform cleaning treatment on the work surface.

[0053] For example, the work surface can be the ground, 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 work surface is a wall or a window, the cleaning equipment 100 can be a window cleaning machine, etc.

[0054] Taking cleaning equipment 100 as an example, a floor scrubber is suitable for cleaning hard floors and can perform dust collection, mopping, and washing functions. Please refer to [link / reference]. Figure 1The cleaning device 100 includes a cleaning head 10 and a body 20 that cooperates with the cleaning head 10. The body 20 has a built-in water tank containing cleaning fluid. After the cleaning device 100 is started, the cleaning fluid in the water tank is delivered to the cleaning head 10 through a pipe to wet the cleaning head 10. The wet cleaning head 10 generates friction with the surface to be cleaned by rotating, and through friction and the cleaning fluid, it separates stains (such as oil stains, sauces, coffee stains, soup, etc.) from the ground, thus achieving the effect of cleaning the surface. At the same time, the cleaning device 100 also has a wastewater collection module for suctioning wastewater. The collection module includes a wastewater tank and a motor. When the motor is working, it keeps the wastewater tank, which is connected to the floor brush assembly through a suction pipe, under negative pressure. The cleaning fluid containing dissolved stains can be suctioned into the wastewater tank through the suction pipe. The wastewater tank can be installed inside the body 20.

[0055] The cleaning solution can be at room temperature or at high temperature after heat treatment. The cleaning head 10 cleans the floor by applying the cleaning solution. The temperature of the cleaning solution further enhances the dissolution rate of stains, thereby improving the cleaning efficiency of the cleaning head 10. Simultaneously, the high-temperature cleaning solution also has a certain bactericidal function, which can disinfect the floor to some extent.

[0056] Please refer to the cleaning head 10 provided in this application embodiment. Figures 2-9 The cleaning head 10 maintains a consistently good cleaning effect on the floor, and its cleaning performance does not significantly decrease over time, further improving the user experience.

[0057] Figure 2 This is a schematic diagram of the structure of the cleaning head 10 provided in the embodiments of this application. Figure 3 This is a partial structural diagram of the cleaning head 10 provided in an embodiment of this application under a certain extreme state.

Figure 8 for Figure 7 A schematic diagram of the axial cross-sectional structure. Figure 9 for Figure 8 Enlarged view of the structure of region B in the middle. Figure 10 for Figure 7 Cross-sectional view.

[0058] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 This application provides a cleaning head 10, which can be applied to a cleaning device 100.

[0059] Specifically, the cleaning head 10 includes a cleaning component 1 and a floating water distribution unit 2 that cooperates with the circumferential surface of the cleaning component 1. The floating water distribution unit 2 is used to press the surface of the cleaning component 1 to ensure that the cleaning liquid flowing to the surface of the cleaning component 1 can fully penetrate into the water-absorbing structure of the cleaning component 1 (such as the bristles, sponge, etc. of the cleaning component 1), so that the working surface 101 of the cleaning component 1 with cleaning function can be evenly wetted by the cleaning liquid, and to avoid the cleaning component 1 from being affected by insufficiently wetted by the cleaning liquid.

[0060] Specifically, the cleaning component 1 is a roller brush-shaped cleaning product with a first axis. In use, the cleaning component 1 can rotate around the first axis and continuously contact the surface to be cleaned during this process, generating friction to achieve cleaning. The floating water distribution unit 2 is located on the outer side of the cleaning component 1 in the circumferential direction and includes a connected water distribution assembly 21 and a driving component 22. The driving component 22 applies a driving force to the water distribution assembly 21 to drive the water distribution assembly 21 to displace it toward the cleaning component 1, so that the water distribution assembly 21 always remains in contact with the surface of the cleaning component.

[0061] With daily use, the cleaning component 1 will experience wear due to prolonged contact and friction with the surface to be cleaned, resulting in a reduction in its radial dimension. In this embodiment, the water distribution component 21 can compensate for the wear of the cleaning component 1 under the drive of the drive component 22. When the radial dimension of the cleaning component 1 decreases due to wear, the water distribution component 21 can move towards the axis of the cleaning component 1 to maintain contact with the circumferential surface of the cleaning component 1.

[0062] It should be noted that the cleaning component 1 has a working surface 101. The aforementioned bristles and other structures capable of absorbing an appropriate amount of cleaning liquid extend around at least part of the circumferential sidewall of the cleaning component 1 to form the working surface 101. In the first axial direction, the size of the water distribution component 21 is greater than or equal to the size of the working surface 101 to ensure that the water distribution component 21 can provide a more comprehensive contact effect with the cleaning component 1. This prevents the cleaning effect of the cleaning component 1 from being affected by poor water distribution or insufficient cleaning liquid content at certain locations on the first axial direction, which could lead to stubborn stains being difficult to remove or water stains remaining after cleaning. This further improves the cleaning effect of the cleaning head 10.

[0063] Please see Figure 4The dotted line in the figure represents the first axis. In the direction of the first axis, at least a portion of the structure of the floating water distribution unit 2 is located above the cleaning component 1, and both ends of the floating water distribution unit 2 protrude outward relative to the working surface 101 of the cleaning component 1, so as to ensure that the floating water distribution unit 2 can act on the working surface 101 of the cleaning component 1 at any position in the direction of the first axis, so as to achieve a better water distribution effect.

[0064] In some embodiments, the drive member 22 includes a spring, and the water distribution assembly 21 cooperates with the spring so that it remains in contact with the surface of the cleaning member 1 under the elastic force of the spring.

[0065] Of course, in other similar embodiments, the driving component 22 can be adjusted to other driving structures as needed. Specifically, the driving component 22 can be set to other structures with elastic energy storage and release effects, such as torsion springs, leaf springs, etc., which can achieve passive driving; or, the driving component 22 can also be set to a structure with active driving function, such as a linear motion mechanism driven by a motor.

[0066] The structure of the cleaning head 10 provided in this embodiment will be described below using the driving component 22, which includes a spring, as an example.

[0067] When the spring is at its compression limit, the radial dimension of the cleaning component 1 that can be fitted is at its maximum. As the cleaning component 1 gradually wears down, the spring gradually releases energy and drives the water distribution assembly 21 to maintain contact with the surface of the cleaning component 1 until the spring has completely released energy. At this point, the cleaning component 1 has reached its maximum wear. In order not to affect its cleaning effect, it is recommended to replace the cleaning component 1.

[0068] Figure 3 , Figure 4 , Figure 5 and Figure 6 The spring is in its compression limit state. Figure 7 , Figure 8 , Figure 9 and Figure 10 The spring is in a fully released state. To facilitate observation of the state changes of the floating uniform water unit 2, Figures 3-10 The radial dimensions of the cleaning component 1 remain consistent.

[0069] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6At least a portion of the floating water distribution unit 2 is located above the cleaning component 1 to facilitate applying pressure to the working surface 101 of the cleaning component 1 (for ease of illustration, the water distribution component 21 in the figure is spaced apart from the surface of the cleaning component 1). Of course, in other feasible embodiments, at least a portion of the surface of the floating water distribution unit 2 may be located on the front or rear side of the cleaning component 1 in the rotation direction, and this embodiment does not limit this.

[0070] In some embodiments, the water distribution assembly 21 includes a mounting base 212 and a water distribution element 213, the water distribution element 213 being connected to the mounting base 212 and abutting against the cleaning element 1. For example, the driving element 22 can drive the mounting base 212 to move toward the cleaning element 1 so that the water distribution element 213 abuts against the surface of the cleaning element 1.

[0071] The floating water distribution unit 2 also includes a limiting shell 23.

[0072] Specifically, the water distribution component 21 includes a mounting base 212 and a water distribution element 213. The limiting housing 23 is located on the outer side of the cleaning element 1 in the circumferential direction. The side of the housing facing the cleaning element 1 is formed with an arc surface that matches the circumferential surface of the cleaning element 1, so as to shield the cleaning element 1 within a certain range and to install and accommodate the mounting base 212 and the water distribution element 213 of the water distribution component 21.

[0073] In some embodiments, the water distribution component 213 can be disposed on the side of the limiting housing 23 facing the cleaning component 1 by means of the mounting base 212, and can move within a certain range relative to the limiting housing 23 under the drive of the driving component 22, so as to abut against the cleaning component 1 with different wear conditions or different radial dimensions.

[0074] In this embodiment, the water distribution element 213 and the mounting base 212 are both installed on the side of the limiting housing 23 facing the cleaning element 1.

[0075] Please see Figure 4 and Figure 5 In this embodiment, the number of mounting bases 212 is at least two, and the water distribution component 213 is connected to the mounting base 212 at different positions on the first axis to achieve contact and cooperation with the cleaning component 1.

[0076] Please see Figure 4 There are two mounting bases 212, which are respectively connected to both ends of the water distribution component 213 in the straight extension direction of the first axis. That is, the two mounting bases 212 are respectively set at one end of the cleaning component 1 in the direction parallel to the first axis.

[0077] In this embodiment, the water distribution member 213 is a columnar structure that abuts against the surface of the cleaning member 1 and extends in a direction parallel to the first axis.

[0078] When the cleaning head 10 is working, the cleaning component 1 rotates around the first axis and cleans the surface to be cleaned. At this time, the water distribution component 213 can keep in contact with the working surface 101 of the cleaning component 1 under the driving force applied by the driving component 22. In this process, by uniformly applying pressure to any position of the working surface 101 of the cleaning component 1 in the direction of the first axis, the water absorbed at the above-mentioned position meets the requirements. There is no situation of failure to wet or excessive water content, thereby ensuring that the water can be evenly distributed on the working surface 101 of the cleaning component 1, ensuring the consistency of its water distribution effect, effectively avoiding the problem of insufficient water supply and / or excessive water supply on the working surface 101 of the cleaning component 1, effectively improving the cleaning effect and reducing water stains.

[0079] After the cleaning component 1 has been used for a certain period of time and has worn down, the driving component 22 can move the water distribution component 213 closer to the cleaning component 1 by driving the mounting base 212 towards the side closer to the cleaning component 1, and keep it in contact with the surface of the cleaning component 1. At this time, the water distribution component 213 can make appropriate displacement according to the degree of wear of the cleaning component 1 to a certain extent, so as to ensure that the circumferential surface of the water distribution component 213 can always maintain good contact with the surface of the cleaning component 1, thereby effectively improving the stability and reliability of the cleaning head 10, and ensuring that the cleaning head 10 can still maintain a good cleaning effect after a certain period of use.

[0080] Of course, in some embodiments, the water distribution component 213 may be provided with an annular groove as needed, and the water distribution component 213 may cooperate with the mounting base 212 through the annular groove.

[0081] In some embodiments, to minimize the wear caused by the water distribution element 213 on the working surface 101 of the cleaning element 1, the surface of the water distribution element 213 that contacts the cleaning element 1 can be configured as an arc-shaped surface. In this case, the water distribution element 213 has a cylindrical structure. Please refer to [link to relevant documentation]. Figure 4 , Figure 5 and Figure 6 .

[0082] It should be noted that the aforementioned driving force can push the mounting base 212 to move in a direction perpendicular to the first axis, thereby ensuring that the water distribution component 213 can tightly abut against the working surface 101 of the cleaning component 1. Please refer to... Figure 7 , Figure 8 , Figure 9 and Figure 10 .

[0083] In some embodiments, the extension line of the displacement trajectory of the mounting base 212 is orthogonal to the first axis, so as to better ensure that the water distribution component 213 can make precise contact with the working surface 101 of the cleaning component 1 at a suitable angle and position, and achieve a better water distribution effect.

[0084] In this embodiment, the displacement range of the mounting base 212 and the water distribution element 213 is affected by the driving element 22. Please refer to... Figure 5 , Figure 6 and Figure 9 , Figure 10 The water distribution component 213, which abuts against the cleaning component 1, has two extreme positions in its direction of movement. It should be noted that, for ease of observation, the radial dimensions of the cleaning component 1 are uniform in the figure. Figure 5 and Figure 6 The water distribution component 213 failed to maintain contact with the cleaning component 1.

[0085] The limiting housing 23 has a guide limiting hole 231. The mounting base 212 can pass through the guide limiting hole 231 and be movably connected to the limiting housing 23. The water distribution component 213 is connected to the end of the mounting base 212 facing the cleaning component 1. The driving component 22 is located on the side of the limiting housing 23 facing the cleaning component 1, and its two ends are connected to the limiting housing 23 and the mounting base 212 respectively, so as to provide the mounting base 212 with a driving force away from the limiting housing 23. The water distribution component 213 can abut against the surface of the cleaning component 1 under the action of the driving force.

[0086] Please see Figure 5 At this point, the gap between the water distribution component 213 and the limiting housing 23 is minimal (or they can remain in contact). The radial dimension of the cleaning component 1, which cooperates with the water distribution component 213 in this state, is relatively large, and the driving component 22 is in a pressurized, energy-storing state. Taking the driving component 22 as a spring as an example, the spring is in a pressurized, energy-storing state. After the external force is removed or reduced, at least a portion of the stored elastic potential energy can be released and converted into kinetic energy to drive the mounting base 212 to move towards the side closer to the cleaning component 1. At this time, the mounting base 212 can drive the water distribution component 213 to move synchronously to maintain contact with the cleaning component 1.

[0087] In some embodiments, the mounting base 212 and the water distribution component 213 can be an integral structure; of course, the mounting base 212 and the water distribution component 213 can also be set as separate structures as needed to help reduce the installation difficulty and processing cost of the mounting base 212 and the water distribution component 213.

[0088] Specifically, the mounting base 212 includes a guide portion 2121, a fastening bolt 2122, and a mounting portion 2123, wherein the guide portion 2121 and the mounting portion 2123 are integrally formed, and the fastening bolt 2122 is detachably connected to the guide portion 2121.

[0089] Please see Figure 5The guide part 2121 can pass through the guide limiting hole 231 opened on the limiting housing 23 and be installed on the limiting housing 23. The fastening bolt 2122 is movably connected to one end of the guide part 2121 that passes through the limiting housing 23 and is combined with the guide part 2121 to achieve the limiting cooperation with the limiting housing 23.

[0090] Specifically, the side of the limiting housing 23 facing the cleaning component 1 is defined as the first surface, and the side facing away from the cleaning component 1 is defined as the second surface. The mounting base 212 can abut against the first surface through the mounting part 2123 and against the second surface through the fastening bolt 2122 to achieve a limiting fit with the limiting housing 23.

[0091] The drive member 22, fitted onto the guide portion 2121, can provide a force to the guide portion 2121 to move towards the side closer to the cleaning member 1. Figure 5 and Figure 6 In the middle, the mounting base 212 abuts against the first surface of the limiting housing 23.

[0092] As the usage time increases, the cleaning component 1 will experience some wear, which will manifest as a decrease in its radial dimension. At this time, the driving component 22 can drive the mounting base 212 and the water distribution component 213 to move toward the side closer to the cleaning component 1 so that the water distribution component 213 can always maintain contact with the surface of the cleaning component 1.

[0093] Please see Figure 9 and Figure 10 ,and Figure 5 and Figure 6 In contrast, both the mounting base 212 and the water distribution component 213 move toward the side closer to the cleaning component 1. At this time, the distance between the water distribution component 213 and the limiting housing 23 increases significantly. At this time, the fastening bolt 2122 abuts against the second surface of the limiting housing 23.

[0094] In some embodiments, the fastening bolt 2122 can be detachably connected to the guide portion 2121. For example, the guide portion 2121 can be provided with a threaded hole 21211, in which case the fastening bolt 2122 can be connected to the guide portion 2121 by a threaded connection.

[0095] In some embodiments, the guide portion 2121 is further provided with a mounting groove 21212 for accommodating at least a portion of the drive member 22, the mounting groove 21212 being located on the side of the guide portion 2121 for connecting with the mounting portion 2123.

[0096] Specifically, the mounting groove 21212 is an annular structure. Taking the driving component 22 as a spring as an example, the driving component 22 is sleeved on the guide portion 2121 and can abut against the surface of the limiting housing 23.

[0097] Considering that the water distribution component 213 is always in contact with the cleaning component 1, in order to reduce the friction between the water distribution component 213 and the cleaning component 1 and reduce the load on the drive motor used to drive the cleaning component 1 to rotate, in this embodiment of the application, the water distribution component 213 can be movably connected to the mounting base 212 and the water distribution component 213 can rotate relative to the mounting base 212.

[0098] Specifically, the water distribution component 213, which is rotatably connected to the mounting base 212, is a cylindrical structure and can rotate around a second axis, which is parallel to the first axis. In this case, the water distribution component 213 is a cylindrical structure extending along the second axis.

[0099] When the water distribution element 213 is located above the cleaning element 1, the orthographic projection of the water distribution element 213 on the surface to be cleaned at least partially overlaps with the orthographic projection of the first axis on the surface to be cleaned.

[0100] When the cleaning head 10 is in working condition, the cleaning component 1 rotates around the first axis. Correspondingly, the water distribution component 213 that abuts against it can rotate synchronously around the second axis parallel to the first axis under the drive of the cleaning component 1. At this time, the friction between the cleaning component 1 and the water distribution component 213 can be transformed from sliding friction to rolling friction, thereby effectively reducing the frictional resistance experienced by the cleaning component 1 during operation, so as to reduce the load on the drive motor and reduce the rotational noise of the cleaning component 1.

[0101] Please see Figure 9 The mounting part 2123 of the mounting base 212 can be provided with a mounting hole 21231, and the water distribution component 213 can be rotated and engaged with the mounting base 212 through the mounting hole 21231.

[0102] In some embodiments, the mounting hole 21231 is a blind hole formed on the mounting base 212, and the axial end of the water distribution component 213 can be inserted into the mounting hole 21231 to achieve rotational engagement with the mounting portion 2123. The blind hole can be used to limit the water distribution component 213 in the axial direction to prevent the water distribution component 213 from axially displacing when rotating.

[0103] Specifically, the water distribution component 213 and the mounting hole 21231 can be a clearance fit or a rotational fit through a structure such as a bushing or bearing. This embodiment does not limit this, as long as it is ensured that the mounting hole 21231 allows the water distribution component 213 to rotate.

[0104] Please see Figure 9 The radial dimension of the end of the water distribution component 213 in the axial direction is smaller than the radial dimension of other regions in the axial direction except the end, so that the end of the water distribution component 213 can be inserted into the mounting base 212 through the mounting hole 21231 to achieve rotational engagement with the mounting base 212.

[0105] Figure 11This is an assembly diagram of a portion of the floating water distribution unit 2 in the cleaning head 10 provided in this embodiment of the application. Figure 12 for Figure 11 Assembly diagram from another angle.

[0106] The structure of the assembly part of the above-mentioned floating water distribution unit 2 will be described in detail below:

[0107] Please see Figure 11 and Figure 12 To better guide the displacement direction of the mounting base 212, the limiting housing 23 is also provided with a guide side plate 232 and a structural reinforcement 233. The guide side plate 232 is located on the side surface of the limiting housing 23 facing away from the cleaning component 1, and the structural reinforcement 233 is located on the side surface of the limiting housing 23 facing the cleaning component 1. Alternatively, the mounting base 212 can be provided with a guide groove, and the corresponding position of the limiting housing 23 can be provided with a guide protrusion that cooperates with the guide groove; the reverse is also possible.

[0108] Please see Figure 11 A structural reinforcement 233 is provided around the guide limiting hole 231. The drive member 22 can abut against the limiting housing 23 through the structural reinforcement 233. The structural reinforcement 233 helps to enhance the structural strength at the connection between the limiting housing 23 and the drive member 22, helps to reduce the risk of damage to the limiting housing 23 due to long-term stress, and helps to extend the service life and reliability of the limiting housing 23.

[0109] Please see Figure 12 A guide side plate 232 is also provided on the outer periphery of the other end of the guide limiting hole 231.

[0110] Specifically, the guide side plate 232 is connected to the inner wall of the guide limiting hole 231 and extends along the axial direction of the guide limiting hole 231 toward the side opposite to the cleaning component 1. This guide side plate 232 can provide better guidance for the mounting base 212, guiding it to move relative to the limiting housing 23 in a set direction. This further determines the movement path of the mounting base 212 and the water distribution component 213, making the contact position between the water distribution component 213 and the cleaning component 1 more accurate, improving the precision and stability of water distribution, and thus optimizing the cleaning effect.

[0111] The guide side plate 232 can be an annular structure surrounding the guide limiting hole 231, or it can be an arc-shaped plate structure located only in a portion of the circumferential area of ​​the guide limiting hole 231. (See also...) Figure 12 At this time, there are two guide side plates 232, which are symmetrically arranged on both sides of the guide limiting hole 231 in the circumferential direction.

[0112] It is understood that the cleaning head 10 provided in this application embodiment includes a cleaning component 1 and a floating water distribution unit 2. The water distribution component 21 in the floating water distribution unit 2 can always remain in contact with the surface of the cleaning component 1 under the drive of the drive component 22. This ensures that during the rotation of the cleaning component 1, it can always provide continuous pressing pressure to the cleaning component 1 by contacting it, so as to ensure that the cleaning liquid on the surface of the cleaning component 1 can fully wet the surface of the cleaning component 1, thereby achieving a better water distribution effect. When the cleaning liquid has a certain temperature, it can make the temperature of the surface of the cleaning component 1 rise evenly, thereby further improving its cleaning effect. Most importantly, the water distribution component 21 can adapt to cleaning components 1 of different states and sizes under the drive of the drive component 22, so as to ensure that even when the cleaning component 1 has a certain wear or the radial dimension of the cleaning component 1 changes, it can still maintain a good water distribution effect, thereby achieving the purpose of improving the cleaning effect and user experience of the cleaning head 10.

[0113] In addition, the water distribution component 213 in the water distribution assembly 21 can reduce the friction between itself and the cleaning component 1 by rotating relative to the cleaning component 1, thereby reducing wear on the cleaning component 1 and helping to extend the service life of the cleaning component 1; it can also reduce the load on the drive motor used to drive the cleaning component 1 to rotate.

[0114] 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.

[0115] 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.
