[0011] The connector is connected to one of the first driving member and the second driving member.

[0012] In one feasible implementation, the first driving member is connected to the end of the wiper component facing away from the cleaning component, and is used to pull the wiper component away from the cleaning component, so that the wiper component moves from the first position to the second position; the second driving member is elastically connected to the end of the wiper component facing away from the cleaning component, and is used to elastically push the wiper component closer to the cleaning component, so that the wiper component moves from the second position to the first position.

[0015] A guide member is connected to the end of the wiper member facing away from the cleaning member, and the guide member has a first guide groove that mates with the protrusion.

[0016] In response to the rotation of the connecting member, the cam rotates about its own axis to pull the wiper member from the first position to the second position via the guide member.

[0028] In one feasible implementation, the mounting housing is provided with a first limiting protrusion, and the wiper is provided with a limiting groove that cooperates with the first limiting protrusion.

[0029] In response to the wiper moving from the first position to the second position, the limiting groove and the first limiting protrusion move closer to each other.

[0031] In one possible implementation, the cleaning head further includes an electrically connected detection element and a controller, the controller being electrically connected to the drive element;

[0032] The detection element is used to detect the rotation angle between the body and the cleaning head.

[0034] In one feasible implementation, the cleaning head has a self-cleaning state and a shutdown state, and the controller is used to generate a drive signal in response to the state of the cleaning component and output a drive signal to the drive component so that the drive component drives the wiper component to switch between the first position and the second position according to the drive signal.

[0035] Specifically, when the cleaning head is in self-cleaning mode, the wiper is in the first position, and when the cleaning head is in a stopped state, the wiper is in the second position.

[0036] In one feasible implementation, the driving element includes a linear drive mechanism, which includes at least one of a linear drive motor and a lead screw drive mechanism.

[0047] The cleaning head provided in this application includes a cleaning component, a squeegee component, and a driving component. The squeegee component can switch between a first position and a second position under the drive of the driving component, moving closer to or further away from the cleaning component. This improves the problem of indentations caused by prolonged interference between the cleaning component and the squeegee component in the second position, by adjusting the squeegee to separate from the cleaning component or minimize interference. Indentations on the surface of the cleaning head cause additional vibrations and abnormal noises between the high-speed rotating cleaning head and the squeegee component, thus affecting the user experience. This application embodiment improves the above-mentioned abnormal noise problem by reducing the possibility of indentations on the surface of the cleaning component, thereby improving the user experience.

[0048] The cleaning equipment and cleaning system provided in this application include the cleaning head for the cleaning equipment described above.

[0079] Figure 1 This is a schematic diagram of the structure of the cleaning system 1000 provided in an embodiment of this application.

[0080] 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.

[0081] 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. The cleaning device 100 can contact the work surface to be cleaned through the cleaning head 10 and perform cleaning treatment on the work surface.

[0082] 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.

[0083] 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 1 The 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. When 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 components 1 (e.g., cleaning brushes) located on the cleaning head 10 and in direct contact with the ground. The wet cleaning components 1 generate friction with the ground through rotation, and this friction, combined with the cleaning fluid, separates stains (e.g., oil stains, sauces, coffee stains, soup stains, etc.) from the ground, achieving a cleaning effect. Simultaneously, the cleaning device 100 also includes a wastewater collection module, which includes a wastewater tank and a motor. The motor's operation keeps the wastewater tank, which is connected to the floor brush assembly via a suction pipe, under negative pressure, allowing the cleaning fluid containing dissolved stains to be drawn into the wastewater tank through the suction pipe. The wastewater tank can be located within the body 20.

[0084] To further improve the cleaning efficiency of the cleaning component 1, a squeegee 2 is also provided inside the cleaning head 10 for scraping away the sewage inside the cleaning component 1. The squeegee 2 can scrape away the sewage adsorbed inside the cleaning component 1 by wiping the surface of the cleaning component 1. At the same time, it can also peel off the garbage and dirt attached to the surface of the cleaning component 1 and collect them into the sewage tank under the action of the sewage recovery module. Thus, in conjunction with the rotation of the cleaning component 1, the cleaning component 1 is cleaned.

[0085] In related technologies, when the cleaning device 100 is in a stopped (or stationary) state, the cleaning component 1 remains stationary, and the squeegee 2 continuously remains in contact with the surface of the cleaning component 1. After a certain period of use, the surface of the cleaning component 1 will develop indentations due to the prolonged contact of the squeegee 2, resulting in damage to its surface smoothness. When the cleaning device 100 restarts and drives the cleaning component 1 to rotate, the squeegee 2 will generate additional vibrations during contact with the surface of the cleaning component 1, causing the cleaning device 100 to produce a "ticking" noise during operation. This not only affects the cleaning effect of the cleaning device 100 to some extent but also introduces additional cleaning noise. In other words, after a user purchases and uses the aforementioned cleaning device 100 for a certain period of time, the cleaning device 100 will produce abnormal noises during use, seriously affecting the user experience.

[0086] In view of this, in order to solve the above problems and improve the user experience to a certain extent, this application provides a cleaning head 10, a cleaning device 100 having the cleaning head 10, and a cleaning system 1000. The cleaning head provided in this application can change the position of the squeegee 2 according to the rotation angle of the body 20 relative to the cleaning head 10. For example, when the body 20 is in an upright state relative to the cleaning head 10, the position of the squeegee 2 can be changed to avoid indentations on the cleaning element 1 on the cleaning head 10 due to the squeezing of the squeegee 2 after a long period of inactivity.

[0087] Please refer to the structure of the cleaning device 100 having the above-mentioned cleaning head 10. Figure 2 , Figure 2 This is a partial structural schematic diagram of the cleaning device 100 provided in an embodiment of this application. Figure 2 In the drawing, the body 20 of the cleaning equipment 100 is not shown.

[0088] Please see Figure 2 The cleaning device 100 includes a detachably connected cleaning head 10 and a body 20, wherein the cleaning head 10 can be rotatably connected to the body 20 via a connector 4.

[0089] The cleaning device 100 has different usage postures, and based on these postures, it can perform different functions. For example, when the cleaning device 100 is in its initial posture, its body 20 is upright (the angle between the body 20 and the cleaning head 10 is approximately between 70° and 110°). The cleaning device 100 can be in a shutdown mode or docked on the cleaning base station 200 and cooperate with the cleaning base station 200 to be in a self-cleaning mode, charging mode, or shutdown mode, etc. When the body 20 of the cleaning device 100 is tilted (the angle between the body 20 and the cleaning head 10 is approximately between 0° and 70°, excluding 70°) and tilted backward relative to the cleaning head 10, the cleaning device 100 can be in a cleaning mode and can be used to clean the ground.

[0090] In some embodiments, the cleaning head 10 includes a connector 4 for connecting to the body 20, thereby enabling a rotatable connection between the cleaning head 10 and the body 20.

[0091] Please refer to the specific structure of the cleaning head 10. Figures 3-4 ,in, Figure 3 This is a schematic diagram of the internal structure of the cleaning head 10 provided in an embodiment of this application. Figure 4 for Figure 3 Exploded view.

[0092] Please see Figure 3 and Figure 4 Besides the connector 4, the cleaning head 10 also includes a main body, a cleaning element 1, a wiping element 2, and a driving element 3. The main body constitutes at least part of the external structure of the cleaning head 10. The cleaning element 1 is rotatably disposed in a set position on the main body about its own axis. One end of the wiping element 2 points to the outer peripheral sidewall of the cleaning element 1, and the other end is connected to the driving element 3 disposed in the main body. The driving element 3 is used to drive the wiping element 2 to move relative to the cleaning element 1 between a first position and a second position, thereby adjusting the amount of interference between them. Specifically, the amount of interference between the wiping element 2 and the cleaning element 1 in the first position is greater than the amount of interference between the wiping element 2 and the cleaning element 1 in the second position.

[0093] As the wiper component 2 moves from the first position to the second position, the amount of interference between the wiper component 2 and the cleaning component 1 gradually decreases; as the wiper component 2 moves from the second position to the first position, the amount of interference between the wiper component 2 and the cleaning component 1 gradually increases.

[0094] It should be noted that, in this embodiment, when the wiper 2 is in the second position, the wiper 2 can be completely separated from or just in contact with the cleaning component 1, at which point the interference between them is zero. Therefore, the wiper 2 has a first position that contacts and engages with the cleaning component 1 and a second position that is separated from the cleaning component 1.

[0095] Alternatively, the wiper component 2 can be positioned so that it abuts against the cleaning component 1 in the second position, resulting in a small amount of interference between them. Conversely, when the wiper component 2 is in the first position, it abuts against the cleaning component 1 with a larger amount of interference. Therefore, the wiper component 2 has a first position and a second position where it contacts and engages with the cleaning component 1, and the interference between the wiper component 2 and the cleaning component 1 in the first position is greater than the interference between the wiper component 2 and the cleaning component 1 in the second position.

[0096] When the wiper 2 is in the second position, the interference between the wiper 2 and the cleaning component 1 is small or zero. Therefore, the pressure exerted by the wiper 2 on the surface of the cleaning component 1 can be effectively reduced, thereby improving the problem that the surface of the cleaning component 1 is prone to dents due to long-term high-intensity interference with the wiper 2. It can also at least reduce the possibility of dents to a certain extent, or improve the depth of the dents, thereby improving the abnormal noise problem caused by the dents, and thus achieving the goal of improving the user experience.

[0097] It should be noted that the aforementioned drive component 3 can respond to the rotation angle of the body 20 and the cleaning head 10. When the body 20 rotates from the tilted state to the upright state, the drive component 3 can drive the wiper component 2 to move from the first position to the second position, thereby improving the squeezing of the cleaning component 1 by the wiper component 2 when the body 20 is upright. When the body 20 rotates from the upright state to the tilted state, the drive component 3 can drive the wiper component 2 to move from the second position to the first position, thereby allowing the wiper component 2 to maintain a large amount of interference with the surface of the cleaning component 1, ensuring that the wiper component 2 can perform its wiping function normally.

[0098] At this time, with the body 20 upright, the squeegee 2 on the cleaning head 10 is in the second position and maintains a small amount of interference with the cleaning component 1. When the cleaning head 10 is not used for a long time, the squeegee 2 in the second position exerts less pressure on the cleaning component 1, which helps to improve the problem of indentations caused by prolonged pressure on the surface of the cleaning component 1 by the squeegee 2.

[0099] In some embodiments, the drive member 3 can drive the wiper member 2 to translate relative to the cleaning member 1 along a set path, moving between a first position and a second position. When the wiper member 2 is in the first position, it can maintain contact with the surface of the cleaning member 1 to scrape and squeeze the cleaning member 1 when it rotates, facilitating the removal of sewage adsorbed by the cleaning member 1 and dirt adhering to its surface. When the wiper member 2 is in the second position, it can separate from the surface of the cleaning member 1 or maintain a relatively small amount of interference, thereby reducing the possibility of dents forming on the surface of the cleaning member 1 or reducing the depth of dents formed on the surface of the cleaning member 1. This overcomes or improves the problem of abnormal noise caused by vibration between the cleaning member 1 and the wiper member 2 during the use of the cleaning head 10, and ultimately improves the user experience of the cleaning head 10.

[0100] The structure of the cleaning head 10 will be described in detail below, with the driving component 3 driving the wiping component 2 to move in a straight line relative to the cleaning component 1.

[0101] Please see Figure 4 The main body of the cleaning head 10 includes a bottom shell 5, and a first sealing element 7 and a second sealing element 8 are also provided on the main body. The bottom shell 5 forms an installation position and space for installing and / or accommodating the cleaning element 1, the driving element 3 and the connecting element 4, etc. The first sealing element 7 and the second sealing element 8 are respectively located on the upper and lower sides of the wiper element 2.

[0102] In this embodiment, the drive member 3 is connected to the connector 4. In response to the rotation of the connector 4, the drive member 3 can drive the wiper member 2 to switch between a first position and a second position.

[0103] In this embodiment, the driving member 3 includes a first driving member 31 and a second driving member that cooperate with each other, wherein the first driving member 31 is used to drive the wiper member 2 to move from a first position to a second position, and the second driving member is used to drive the wiper member 2 to move from a second position to a first position.

[0104] The first driving member 31 can be connected to the end of the wiper 2 facing away from the cleaning member 1, and is used to pull the wiper 2 away from the cleaning member so that the wiper 2 moves from the first position to the second position; the second driving member is elastically connected to the end of the wiper 2 facing away from the cleaning member 1, and is used to push the wiper 2 closer to the cleaning member 1 by elastic pushing so that the wiper 2 moves from the second position to the first position.

[0105] In this embodiment, to facilitate control of the position of the wiping component 2 based on the posture of the cleaning device 100, the first driving component 31 is connected to the connecting component 4. Please refer to [link to relevant documentation]. Figure 3 and Figure 4 .

[0106] When the body 20 rotates relative to the cleaning head 10, the connecting part 4 connected to the body 20 will rotate with the rotation of the body 20, thereby driving the first driving part 31 to rotate synchronously, thereby driving the wiper part 2 to move from the first position to the second position. At this time, the second driving part can accumulate elastic potential energy as the wiper part 2 moves, and after the connecting part 4 rotates to the appropriate position, it will drive the wiper part 2 to move from the second position to the first position by releasing the elastic potential energy.

[0107] Specifically, the second driving component is set as an elastic reset component 32. The elastic reset component 32 can drive the wiper component 2 to move from the second position to the first position through deformation recovery or deformation. That is, the elastic reset component 32 is the power source for the wiper component 2 to move from the second position to the first position. Moreover, the elastic reset component 32 can respond to the movement of the wiper component 2 from the first position to the second position through deformation or deformation recovery. That is, when the wiper component 2 moves from the first position to the second position, the elastic reset component 32 is passively deformed and stores energy.

[0108] In this embodiment, the elastic reset member 32 is provided to store energy by deforming in response to the movement of the wiper member 2 from the first position to the second position, and to drive the movement of the wiper member 2 from the first position to the second position by deforming and releasing energy.

[0109] Specifically, the first driving component 31 includes a cam 311 located above the bottom shell 5. The cam 311 is fixedly connected to the connecting component 4, which moves with the body 20. The cam 311 and the connecting component 4 move synchronously. When the cam 311 moves, it can drive the wiper component 2 connected to it to move from the first position to the second position. During this process, the elastic reset component 32 stores energy. The elastic reset component 32 includes a mounting housing 321 and an elastic component 322. The mounting housing 321 has a cleaning cavity for accommodating the cleaning component 1. The cleaning component 1 is rotatably confined within the cleaning cavity to achieve the cleaning function of the floor. Part of the structure of the mounting housing 321 is located on the side of the wiper component 2 facing away from the cleaning component 1 and forms a limiting baffle 3211 to cooperate with the wiper component 2 to form a space for mounting the elastic component 322. The elastic component 322 is confined between the limiting baffle 3211 and the wiper component 2 and abuts against the wiper component 2. During the process of the wiper component 2 moving from the first position to the second position, the elastic element 322 stores energy. After the cam 311 is disconnected from the wiper component 2, the deformation of the elastic element 322 is restored and drives the wiper component 2 to move from the first position to the second position.

[0110] In summary, under the interaction of the first driving member 31 and the elastic reset member 32, the wiper member 2 can switch between a first position and a second position relative to the cleaning member 1.

[0111] In some embodiments, the first seal 7 and the second seal 8 can be fixed to both sides of the wiper 2 by bolts. In this case, the first seal 7, the wiper 2, and the second seal 8 are located on the same side of the cleaning head 10 and are arranged sequentially along the circumference of the cleaning head 10, respectively sealing the first side 201 and the second side 202 of the wiper 2. Of course, the first seal 7 and the second seal 8 can be directly fixed to the wiper 2 by bolts, or they can be fixed to the mounting housing 321 by bolts. It is only necessary to ensure that the first seal 7 and the second seal 8 are located on both sides of the wiper 2. This embodiment does not limit the actual installation method and installation structure of the first seal 7 and the second seal 8.

[0112] The structure of the squeegee 2 in the cleaning head 10 when it is in the first position is described below.

[0113] Please see Figures 5-9 , Figure 5 This is a top view of the cleaning head 10 provided in the embodiments of this application when the wiping element 2 is in the first position. Figure 6 for Figure 5 Sectional view along line AA in the middle, Figure 7 for Figure 6 Enlarged view of the structure of region C in the image. Figure 8 for Figure 5 BB-direction sectional view in the middle, Figure 9 for Figure 8 Enlarged view of the structure of region D in the image. Figure 10 for Figure 5 An assembly diagram of the wiper component 2 and the mounting housing 321. Figure 11 for Figure 10 Enlarged view of the structure of region E in the middle. Figure 12 for Figure 5 A cross-sectional view of the assembly of the wiper 2 and the first seal 7.

[0114] Please see Figure 5 , Figure 6 and Figure 9 The cleaning head 10 includes a mounting housing 321 for limiting and accommodating the cleaning component 1. The wiping component 2, which abuts against the cleaning component 1, is located below the mounting housing 321 and connected to the first drive component 31. The first drive component 31 includes a cam 311 and a guide component 312 that cooperate with each other. The cam 311 is connected to the connecting component 4 and can rotate synchronously with the rotation of the connecting component 4. The guide component 312 is connected to the end of the wiping component 2 facing away from the cleaning component 1, and has a first guide groove 3121 for cooperating with the cam 311. The first guide groove 3121 can be a through groove or a recess.

[0115] It should be noted that the aforementioned guide member 312 can be integrally formed with the wiper member 2, or it can be fixedly connected to the wiper member 2 through a fixed connection method disclosed in related technologies such as bonding, snap-fitting, and threaded connection. When the guide member 312 is displaced under the pull of the cam 311, the wiper member 2 connected to the guide member 312 can also move synchronously.

[0116] In response to the rotation of the connector 4 from the inclined position to the upright position, the cam 311 rotates about its own axis and pulls the wiper 2 from the first position to the second position through the guide 312.

[0117] When the wiper component 2 is in the first position, the cam 311 is separated from the first guide groove 3121 on the guide component 312. Please refer to [link / reference]. Figure 8 and Figure 9 .

[0118] Please see Figure 8 One end of the guide member 312 is separated from the cam 311, and the other end passes through the through hole 511 and connects to the wiper member 2. It should be noted that a baffle 51 protrudes from the bottom shell 5. The baffle 51 is located between the first drive member 31 and the wiper member 2 and has a through hole 511 for the guide member 312 to pass through. The guide member 312 can be connected to the wiper member 2 through this through hole 511.

[0119] Specifically, the cam 311 is a cylindrical structure fixed to the connector 4, and a protrusion 3111 is provided on its outer peripheral sidewall. The cam 311 can cooperate with the first guide groove 3121 on the guide member 312 through the protrusion 3111.

[0120] The protrusion 3111 responds to the rotational movement of the cam 311 and can pull the first guide groove 3121 on the guide member 312 to switch the position of the wiper member 2 between the first position and the second position.

[0121] In this embodiment, the number of cams 311 can be one, two, or even more, and the number of guide members 312 is the same as the number of cams 311 and they are arranged in a one-to-one correspondence.

[0122] Please see Figure 5 and Figure 6 There are two cams 311, which are respectively arranged on both sides of the connector 4. Correspondingly, there are two guides 312, which are respectively arranged opposite to the two cams 311. The two guides 312 are symmetrically arranged relative to the wiper 2, thereby providing a more stable pulling force to the wiper 2, pulling the wiper 2 from the first position to the second position.

[0123] In this embodiment, the guide member 312 can be a flat strip structure, one end of which can be limited to the bottom shell 5 by sliding fit and partially located below the cam 311, and the other end can pass through the perforation 511 opened on the baffle 51 and be connected to the wiper member 2.

[0124] Specifically, the aforementioned guide member 312 can be a straight member extending along a fixed straight line, or it can be as follows: Figure 6 The shown is a polygonal component. In Figure 6 In the middle, the guide member 312 includes a horizontal section and a sloping section. The first guide groove 3121 is formed in the horizontal section, and the sloping section is used to pass through the through hole 511 to connect the horizontal section and the wiper member 2. Figure 6 (Not marked in the text).

[0125] When the wiper component 2 is in the first position, please refer to the section on the interference relationship between the wiper component 2 and the cleaning component 1. Figure 7 .

[0126] The mounting housing 321 is partially located above the cleaning component 1 and forms a cleaning cavity for accommodating the cleaning component 1. It extends partially between the cleaning component 1 and the first drive component 31, forming the aforementioned limiting baffle 3211. The elastic member 322 is positioned between the limiting baffle 3211 and the wiper component 2, and maintains contact with both. When the wiper component 2 moves from the first position to the second position, the elastic member 322 is compressed and deformed, accumulating a certain amount of elastic potential energy during this process. When the wiper component 2 is in the second position, the elastic member 322 experiences the highest degree of compression deformation and accumulates the greatest amount of elastic potential energy.

[0127] In response to the rotation of the connecting member 4 from the upright position to the inclined position, the cam 311 rotates in the opposite direction around its own axis and disengages from the guide member 312 (i.e., the two separate). At this point, the driving force exerted by the cam 311 on the wiper member 2 through the guide member 312 to move from the first position to the second position is removed. After the cam 311 separates from the guide member 312, the elastic member 322 recovers its deformation (either partially or completely) and releases its elastic potential energy. Under the action of this elastic potential energy, the wiper member 2 moves from the second position to the first position, and the interference with the cleaning member 1 gradually increases.

[0128] The elastic element 322 can push the wiper element 2 from the second position to the first position and reset it by deforming and restoring energy without applying additional driving force. This not only helps to simplify the device structure, but also makes the reciprocating movement of the wiper element 2 between the first position and the second position smoother and more stable.

[0129] Specifically, in this embodiment, the elastic element 322 includes a spring. Of course, it can also be other components with elastic deformation recovery capability, which will not be described in detail here.

[0130] In order to enable the elastic element 322 to smoothly push the wiper 2 from the second position to the first position, in some embodiments, the number of elastic elements 322 may be at least two and spaced apart along the length of the wiper 2.

[0131] Please see Figure 4 In this embodiment, the number of elastic elements 322 is three.

[0132] In order to better achieve the installation and limiting of the elastic element 322, in some embodiments, the wiper 2 is provided with a recessed receiving groove 21 on the side facing the limiting baffle 3211. The receiving groove 21 is used to accommodate the elastic element 322, and the elastic element 322 limited in the receiving groove 21 abuts against the inner wall of the receiving groove 21.

[0133] Please see Figure 7 At this time, at least part of the structure of the elastic element 322 is confined within the receiving groove 21, and one end of it facing away from the wiper element 2 can abut against the limiting baffle 3211.

[0134] To further improve the assembly reliability of the elastic element 322 and the wiper element 2, please refer to... Figure 7 The middle part of the above-mentioned receiving groove 21 is provided with a guide post 22 pointing to the limiting baffle 3211, and the elastic member 322 is sleeved on the guide post 22 and abuts against the limiting baffle 3211.

[0135] The guide post 22 guides the elastic element 322 and, in conjunction with the receiving groove 21, limits the movement of the elastic element 322. (See also...) Figure 7 Taking the elastic element 322 as a spring as an example, the axial direction of the spring is parallel to the axial direction of the guide post 22.

[0136] With the cooperation of the guide post 22 and the receiving groove 21, the spring can be radially limited, so that the spring can move along the preset axis in the receiving cavity, and the wiper 2 can be moved from the second position to the first position through the elastic deformation of the spring.

[0137] It should be noted that there is a certain gap between the guide post 22 and the limiting baffle 3211. This gap is used to prevent the guide post 22 from being damaged by collision with the limiting baffle 3211 when it moves from the first position to the second position.

[0138] The gap formed between the guide post 22 and the limiting baffle 3211 allows the wiper 2 to move relative to the limiting baffle 3211 between a first position and a second position. That is, when the wiper 2 is in the first position, there is a gap between the guide post 22 and the limiting baffle 3211; when the wiper 2 is in the second position, the guide post 22 and the limiting baffle 3211 are in contact or there is always a certain gap between them.

[0139] Please see Figure 7 The wiper component 2 has a flat, plate-like structure. When the cleaning head 10 is in its normal position, the wiper component 2 has a first side 201 on its upper surface and a second side 202 on its lower surface, with the first side 201 and the second side 202 arranged opposite to each other in the thickness direction of the wiper component 2.

[0140] Considering that the wiper 2 needs to scrape away the wastewater adsorbed inside the cleaning component 1 by pressing against and scraping it, in order to prevent the scraped wastewater from entering the cleaning head 10 through the gap between the wiper 2 and the cleaning component 1 or the mounting housing 321 and contaminating the internal components of the cleaning head 10, a sealing structure needs to be provided on both the first side 201 and the second side 202 of the wiper 2 to ensure the safety of the internal components of the cleaning head 10. In addition, the above-mentioned sealing structure can also reduce the intrusion of foreign objects into the cleaning head 10. The scraped foreign objects and wastewater can be recycled into the wastewater tank by the recycling module.

[0141] In this embodiment, the sealing structure includes the first sealing member 7 and the second sealing member 8 as described above, wherein the first sealing member 7 is located on the first side 201 of the wiper member 2 and abuts against the surface of the first side 201 of the wiper member 2, and the second sealing member 8 is located on the second side 202 of the wiper member 2 and abuts against the surface of the second side 202 of the wiper member 2.

[0142] Please see Figure 7 Under the sealing action of the first seal 7 and the second seal 8, sewage and impurities scraped off the cleaning head 10 by the wiper 2 cannot penetrate into the interior of the cleaning head 10, which helps to ensure the safety of the internal components of the cleaning head 10. In addition, the cooperation of the first seal 7 and the second seal 8 can also enable the wiper 2, which is movable relative to the cleaning head 10, to have a better sealing effect, preventing sewage and other contaminants from entering the cleaning head 10 as the wiper 2 moves.

[0143] Specifically, the first sealing element 7 may include a mounting plate and a sealing strip. The mounting plate extends along the length of the wiper component 2 and is consistent with or substantially consistent with the length of the wiper component 2. At least a portion of the sealing strip is located on the side of the mounting plate facing the wiper component 2, and the lip of the sealing strip for sealing points towards the wiper component 2. This ensures that after the mounting plate is installed in place, the lip of the sealing strip can abut against the first side 201 of the wiper component 2 and undergo elastic deformation, thereby achieving a seal on the first side 201 of the wiper component 2. The sealing strip can be fixed to the mounting plate by snap-fit, bolt fixing, or adhesive bonding, which will not be elaborated here.

[0144] The structure of the second seal 8 is basically the same as that of the first seal 7.

[0145] In this embodiment, at least one of the first seal 7 and the second seal 8 can be fixed to the mounting housing 321 by bolts to form a sealed connection with respect to the wiper 2.

[0146] Specifically, the mounting housing 321 can be provided with a threaded hole, and the first seal 7 can be fixedly connected to the mounting housing 321 by a fastener (such as a screw) that is threaded into the threaded hole. Please refer to [link to relevant documentation]. Figure 7 .

[0147] Specifically, the mounting housing 321 may be provided with a first limiting protrusion 3212 protruding on the side facing the wiper component 2, and the wiper component 2 may be provided with a limiting groove 23 that mates with the first limiting protrusion 3212. Please refer to [link / reference]. Figure 10 and Figure 11 A threaded hole is formed in the first limiting protrusion 3212, and the second seal 8 can be fixedly connected to the mounting housing 321 by a fastener (such as a screw) that is threaded to the threaded hole.

[0148] In response to the wiper 2 moving from the first position to the second position, the first limiting protrusion 3212 and the wall of the limiting groove 23 approach each other.

[0149] Please see Figure 11 The mounting housing 321 also has a second limiting protrusion 3213 protruding on the side facing the wiper 2, which is spaced apart from the first limiting protrusion 3212. The wiper 2 is provided with a limiting through hole 24 that cooperates with the second limiting protrusion 3213. The second limiting protrusion 3213 passes through the limiting through hole 24 to provide a certain guiding effect for the movement of the wiper 2 between the first position and the second position.

[0150] Specifically, the limiting perforation 24 is set as a strip-shaped hole extending along the path direction between the first position and the second position.

[0151] Furthermore, considering that both the first seal 7 and the second seal 8 are in sealing engagement with the wiper component 2, in order to further enhance the guiding effect on the movement of the wiper component 2 between the first position and the second position, at least one of the first seal 7 and the second seal 8 is provided with a second guide groove 9, and the wiper component 2 is provided with a guide protrusion 25 that mates with the second guide groove 9. Please refer to [link / reference]. Figure 12 At this time, the second guide groove 9 is formed on the first seal 7. When the wiper 2 moves between the first position and the second position, the guide protrusion 25 translates relative to the second guide groove 9.

[0152] Without affecting the sealing effect of the sealing structure, the second guide groove 9 can be either a through groove or a recessed structure. Please refer to... Figure 12 At this time, the surface of the second guide groove 9 facing the guide protrusion 25 of the wiper 2 is partially recessed to form the second guide groove 9.

[0153] Along the thickness direction of the wiper 2, the orthographic projection of the second guide groove 9 on the wiper 2 and the orthographic projection of the limiting perforation 24 on the wiper 2 are arranged alternately.

[0154] When the wiper component 2 moves from the first position to the second position under the drive of the first drive component 31, please refer to Figures 13-17 .

[0155] Figure 13 This is a top view of the cleaning head 10 provided in the embodiments of this application when the wiping element 2 is in the second position. Figure 14 for Figure 13 FF section view, Figure 15 for Figure 14 Enlarged view of the structure of region H in the middle. Figure 16 for Figure 13 The GG section view in the middle, Figure 17 for Figure 16 Enlarged view of the structure of region I in the image.

[0156] The structure of the squeegee 2 in the cleaning head 10 when it is in the second position is described below.

[0157] Please see Figures 13-17 As the connecting member 4 rotates, the cam 311 rotates synchronously. When the cam 311 rotates around its own axis, the protrusion 3111 formed on the outer peripheral sidewall of the cam 311 rotates synchronously with the cam 311 until it abuts against the inner wall of the first guide groove 3121 formed on the guide member 312. As the cam 311 continues to rotate, the contact point between the outer peripheral contour of the protrusion 3111 and the inner sidewall of the guide groove undergoes radial displacement along the cam 311, providing a certain pushing force on the inner wall of the first guide groove 3121, and driving the first guide groove 3121 to move along a preset path. Please refer to [link to relevant documentation]. Figure 16 and Figure 17 At this time, the guide member 312 with the first guide groove 3121 can move under the pull of the cam 311 and drive the wiper member 2 to move from the first position to the second position.

[0158] It should be noted that the contour curve of the protrusion 3111 of the cam 311 is adapted to the extension direction of the guide groove to ensure that the displacement trajectory of the guide groove is stable during the rotation of the cam 311.

[0159] When the wiper component 2 is in the second position, the relative positional relationship between the wiper component 2 and the cleaning component 1 is shown in the figure. Figure 14 and Figure 15 .and Figure 7 In comparison, the interference between the wiper component 2 and the cleaning component 1 is significantly reduced at this time. Meanwhile, the elastic component 322, which is located between the limiting baffle 3211 and the wiper component 2, is in a state of compression deformation.

[0160] Of course, in other similar embodiments, the wiper 2 and the cleaning component 1 located in the second position can also be set to be in a separated state, in which case there is no interference between the wiper 2 and the cleaning component 1.

[0161] In other similar embodiments, the drive unit 3 can also obtain the rotation angle between the body 20 and the cleaning head 10 through other structures to achieve control of the position of the wiping component 2.

[0162] Figure 18 A schematic diagram showing the connection between the drive unit 3, the controller 62, and the detection unit 61 in a cleaning head 10 provided in another embodiment of this application.

[0163] Specifically, the cleaning head 10 also includes an electrically connected detection element 61 and a controller 62, wherein the controller 62 is electrically connected to the drive element 3. (See [link to relevant documentation]). Figure 18 .

[0164] exist Figure 18 In this configuration, the detection element 61 is used to detect the rotation angle between the body 20 and the cleaning head 10. In response to the detection result of the detection element 61 (i.e., the rotation angle of the body 20 relative to the cleaning head 10), the controller 62 generates a drive signal and outputs a drive signal to the drive element 3, so that the drive element 3 drives the wiper element 2 to switch between a first position and a second position according to the drive signal.

[0165] Specifically, when the rotation angle between the body 20 and the cleaning head 10 is greater than or equal to a set angle, the controller 62 generates and outputs a first control signal to the drive unit 3; when the rotation angle between the body 20 and the cleaning head 10 is less than the set angle, the controller 62 generates and outputs a second control signal to the drive unit 3. The set angle can be adjusted according to design requirements; in this embodiment, the set angle can be set to 70°.

[0166] Under the control of the first control signal, the drive unit 3 drives the wiper component 2 to move from the first position to the second position (which can also be understood as switching from the first position to the second position); under the control of the second control signal, the drive unit 3 drives the wiper component 2 to move from the second position to the first position (which can also be understood as switching from the second position to the first position).

[0167] It should be noted that when the body 20 is in an upright position relative to the cleaning head 10, the controller 62 generates a first control signal; when the body 20 is in an inclined position relative to the cleaning head 10, the controller 62 generates a second control signal.

[0168] Specifically, the aforementioned detection component 61 includes at least one of a photoelectric angle detection component and a magnetoelectric angle detection component.

[0169] Taking a magnetoelectric angle detection device as an example, the detection device 61 can realize angle detection based on changes in the magnetic field, such as a Hall angle detector.

[0170] In some embodiments, when the body 20 is in an upright position relative to the cleaning head 10, the squeegee 2 is in a second position.

[0171] Considering the need for the cleaning head 10 to self-clean in an upright position, in some embodiments, the cleaning head 10 is configured to have a self-cleaning state and a shutdown state. The controller 62 generates a drive signal in response to the working state of the cleaning component 1 and outputs a drive signal to the drive component 3, so that the drive component 3 drives the wiper component 2 to switch between a first position and a second position according to the drive signal; wherein, when the cleaning head 10 is in the self-cleaning state, the wiper component 2 is in the first position, and when the cleaning head 10 is in the shutdown state, the wiper component 2 is in the second position.

[0172] Please see Figure 19 , Figure 19 This is a schematic diagram showing the connection between the drive unit 3 and the controller 62 in a cleaning head 10 provided in another embodiment of this application.

[0173] It should be noted that when the cleaning head 10 is in self-cleaning mode or in the off mode, the angle between the cleaning head 10 and the body 20 is greater than or equal to the set angle. At this time, the body 20 is in an upright state and the wiper 2 is in the second position.

[0174] Considering that the interference between the wiping component 2 and the cleaning component 1 in the second position is small when the body 20 is upright, in order to avoid affecting the self-cleaning effect of the cleaning head 10, in this embodiment, a controller 62 is provided to adjust the position of the wiping component 2 according to the working state of the cleaning head 10.

[0175] In response to the state of the cleaning head 10, the controller 62 controls the wiper 2 to switch between a first position and a second position via the drive 3.

[0176] When the cleaning head 10 is in the stopped state, the drive unit 3 drives the wiper 2 to move from the first position to the second position, thereby moving the wiper 2 away from the cleaning part 1 to reduce the amount of interference between them or to separate them. This can effectively reduce the contact force exerted by the wiper 2 on the surface of the cleaning part 1, thereby reducing the depth of the indentation formed on the surface of the cleaning part 1 or helping to reduce the possibility of indentation formed on the surface of the cleaning part 1 due to the pressure of the wiper 2. When the cleaning head 10 is in the self-cleaning state, it is necessary to clean the surface of the cleaning part 1. At this time, the drive unit 3 drives the wiper 2 to move from the second position to the first position to achieve efficient cleaning of the cleaning part 1. After the cleaning head 10 finishes self-cleaning, the drive unit 3 drives the wiper 2 to move from the first position to the second position.

[0177] In some embodiments, the driving member 3 may include the cam 311 and the elastic reset member 32 described above. In this case, the cam 311 can rotate within a certain range under the drive of the corresponding drive motor to drive the wiper member 2 to move from the first position to the second position. The cam 311 is rotatably connected to the connecting member 4.

[0178] In other similar embodiments, the driving component 3 can be configured as a linear driving mechanism that can drive the wiper component 2 to reciprocate along a fixed path within a certain range.

[0179] Specifically, the aforementioned linear drive mechanism includes at least one of a linear drive motor and a lead screw drive mechanism. This linear drive mechanism can drive the wiper component 2 to reciprocate between a first position and a second position under the drive of the controller 62.

[0180] It is understood that in this embodiment, the cleaning head 10 can switch and adjust the position of the wiping element 2 by changing the rotation angle between the body and the cleaning head, thereby improving the problem of indentations caused by long-term interference and contact between the cleaning element 1 and the wiping element 2 in the upright state of the cleaning head 10. This embodiment can improve the problem of abnormal noise during use of the cleaning head 10 by reducing the possibility of indentations forming on the surface of the cleaning element 1 or reducing the depth of indentations formed on the surface of the cleaning element 1, thus achieving the goal of improving the user experience.

[0181] The descriptions of the various embodiments above tend to emphasize the differences between them. Similarities or commonalities can be referenced interchangeably, and for the sake of brevity, they will not be repeated here. The above descriptions are merely preferred embodiments of this application and are not intended to limit the application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
