Detailed Implementation

[0066] The embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this disclosure.

[0067] It should be noted that in the embodiments of this disclosure, the orientations or positional relationships of "first direction," "second direction," and "third direction" are based on the orientations or positional relationships shown in the accompanying drawings. It should be understood that these orientational terms are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. In all the accompanying drawings of the embodiments of this disclosure, the first direction X, the second direction Y, and the third direction Z are bidirectional, and the arrows do not indicate directions limited to one direction. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0068] In the description of the embodiments of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure based on the specific circumstances.

[0069] In the embodiments disclosed herein, unless otherwise expressly specified and limited, the first feature “on” the second feature may be in direct contact with the first feature and the second feature, or indirect contact between the first feature and the second feature through an intermediate medium.

[0070] In the description of this specification, references to terms such as "some embodiments," "exemplary," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the embodiments of this disclosure. 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, those skilled in the art can combine the different embodiments or examples described in this disclosure and the features of those different embodiments or examples without contradiction.

[0071] In related technologies, the cleaning components of cleaning equipment may have garbage or residual liquid attached to them. During the process of the cleaning equipment moving to the base station or moving from the cleaned surface to the surface to be cleaned, the garbage or residual liquid may fall onto the ground or the cleaned surface, causing pollution and adversely affecting the cleaning effect.

[0072] In view of this, the present disclosure provides a cleaning device that can collect debris or residual liquid on cleaning components during the transfer of the cleaning device, reducing the possibility of debris or residual liquid adhering to the cleaning components falling onto the cleaned surface or ground and causing pollution. The cleaning device 100 includes, but is not limited to, floor scrubbers, sweepers, combined sweeper and scrubber machines, or maintenance machines.

[0073] Exemplarily, the cleaning device 100 includes a wheel assembly, which can be a driving wheel mechanism that provides walking power or a driven wheel mechanism that rotates following the driving wheel; this disclosure does not impose any limitations. The wheel assembly includes wheels, which can be driving wheels or driven wheels. The amount of interference between the cleaning component and the ground can be adjusted by adjusting the height of the wheels relative to the device body. Exemplarily, the wheels include, but are not limited to, rollers, track wheels, Mecanum wheels, etc.

[0074] For ease of description, in the following embodiments, debris or residual liquid on the cleaning component are collectively referred to as easily falling objects, such as hair, dust, debris, cleaning fluid, conditioning agent, dirty water or clean water, etc.; the surface to be cleaned, the cleaned surface, or the carpet laid on the ground are collectively referred to as the walking surface; cleaning operations and maintenance operations are collectively referred to as cleaning operations. To facilitate the demonstration of the main structure, the accompanying drawings in each specification have been simplified. Among them, Figures 1, 8, 10-11, 14, and 20 all show the cleaning component 20, while the cleaning component is omitted in the other figures.

[0075] In some embodiments, referring to Figures 1 and 2, the cleaning device 100 includes a device body 10, a cleaning component 20, and a shielding component 30. The device body 10 has a first receiving cavity 10a, which has a first open end 10a1 that opens towards a walking surface. The cleaning component 20 is disposed on the device body 10 and is movable relative to the device body 10, having a retracted state contained within the first receiving cavity 10a and an operating state at least partially protruding from the first open end 10a1. The shielding component 30 is disposed on the device body 10 and is movable relative to the device body 10; wherein, when the cleaning component 20 is in the retracted state, the shielding component 30 can shield the first open end 10a1; and when the cleaning component 20 is in the operating state, the shielding component 30 can avoid the first open end 10a1.

[0076] The main body 10 is used to install and support other components of the cleaning equipment 100. It is understood that the main body 10 in all the accompanying drawings of this embodiment is only a partial structural illustration, and the specific structure of the main body 10 can be adaptively designed according to functional requirements. For example, the outer contour of the main body 10 can be square or circular.

[0077] The cleaning component 20 is used to clean or maintain the surface to be cleaned. For example, the cleaning component 20 can be used to sweep up debris, including but not limited to hair, dust, or crumbs; it can also be used for mopping, washing, or waxing. The cleaning component 20 may include a roller brush or a disc brush, wherein the roller brush may be simply referred to as a roller brush. This embodiment of the disclosure is described using a cleaning component 20 including a roller brush as an example. The length direction of the roller brush is along the rotation axis of the roller brush and parallel to the first direction X.

[0078] For example, the cleaning device 100 includes a cleaning component 20 and a drive component. Under the drive of the drive component, the cleaning component 20 rolls relative to the walking surface, collecting dust, debris, hair and other garbage from the walking surface, or uniformly applying a cleaning agent to the ground.

[0079] The first receiving cavity 10a is used to accommodate the cleaning component 20. When the cleaning device 100 performs a cleaning operation, the cleaning component 20 can extend downward from the first open end 10a1 to contact the walking surface to clean it. After the cleaning operation is completed, the cleaning component 20 can move relative to the device body 10 and retract from the first open end 10a1 into the first receiving cavity 10a. The direction of movement of the cleaning component 20 extending downward from the first open end 10a1 includes, but is not limited to, vertically downward along the third direction Z, or obliquely downward at a certain angle to the third direction Z. For example, the third direction Z can be an up-down direction.

[0080] The shielding component 30 is used to shield the first open end 10a1 to catch any loose objects on the cleaning component 20. The shielding component 30 can shield the portion of the first open end 10a1 corresponding to the cleaning component 20, or it can shield and completely close the first open end 10a1. During cleaning operations, the shielding component 30 avoids the first open end 10a1 to prevent interference with the cleaning operation of the cleaning component 20. After the cleaning operation is completed, the cleaning component 20 moves into the first receiving cavity 10a. The shielding component 30, positioned below the first open end 10a1, reduces the likelihood of loose objects on the cleaning component 20 falling onto the walking surface.

[0081] The shielding component 30 can achieve shielding in any way, as long as it can support the cleaning component 20 when it is in the retracted state and does not interfere with the operation of the cleaning component 20 during cleaning. For example, the shielding component 30 can be unfolded in a flip-up, curtain-like, or roller-like manner to achieve shielding.

[0082] The cleaning device 100 provided in this embodiment allows the shielding component 30 to avoid interfering with the cleaning operation of the cleaning component 20 when the cleaning component 20 is performing cleaning work. After the cleaning operation, the shielding component 30 can cover the first open end 10a1, reducing the possibility of loose objects on the cleaning component 20 falling onto the walking surface. This improves the cleaning effect and reduces the possibility of the cleaning component 20 contaminating the walking surface after the cleaning operation, thus reducing the need for rework and repeated cleaning.

[0083] In some embodiments, referring to FIG1, the cleaning device 100 further includes a floating mechanism 70 and a connecting mechanism. The floating mechanism 70 is disposed on the device body 10 and includes an abutment 71 that can remain in contact with the cleaning component 20, which includes a roller brush. The connecting mechanism is connected to the wheel assembly and can move with the abutment 71 so that the wheel assembly can move relative to the device body 10.

[0084] When the roller brush wears down and its diameter decreases, the abutment 71 moves toward the roller brush. The connecting mechanism can move with the abutment 71, thereby driving the walking wheel assembly to move upward relative to the main body 10 of the equipment. In this way, the amount of interference of the roller brush with the surface to be cleaned can be maintained, the service life of the roller brush can be extended, which is equivalent to increasing the service life of the roller brush and reducing the use and maintenance costs of the cleaning equipment 100.

[0085] In some embodiments, referring to FIG2, the first receiving cavity 10a also has a second open end 10a2 that is open to the periphery of the device body 10. The first open end 10a1 and the second open end 10a2 are connected. The shielding component 30 is left open at the second open end 10a2 so that the cleaning component 20 can at least partially protrude from the second open end 10a2.

[0086] The cleaning component 20 can protrude at least partially from the second open end 10a2, thereby expanding the cleaning range of the cleaning component 20. For example, the cleaning component 20 protruding from the second open end 10a2 can clean debris in corners, reducing blind spots that the cleaning device 100 cannot clean on the surface to be cleaned, and reducing the possibility that the cleaning component 20's cleaning range is limited by the shape of the device body 10. When the cleaning device 100 is performing cleaning operations, the shielding component 30 is left open at the second open end 10a2 and can avoid the first open end 10a1 to prevent interference with the cleaning component 20's cleaning operations.

[0087] It is understandable that the driving method for switching the position of the shielding component 30 between shielding the first open end 10a1 and avoiding the first open end 10a1 is not limited. It can be driven manually or by a driving component.

[0088] For example, referring to Figures 1 and 2, the shielding assembly 30 includes at least one first mounting base 31, a flip-up shielding member 32, and a first driving member 33. The first mounting base 31 is disposed on the device body 10; the flip-up shielding member 32 is rotatably disposed on the first mounting base 31; the first driving member 33 is drivenly connected to the flip-up shielding member 32 so that the flip-up shielding member 32 can rotate relative to the first mounting base 31 and can shield or avoid the first open end 10a1.

[0089] The first mounting base 31 is used for mounting the flip-up shield 32. The first driving member 33 is used to provide power for the rotation of the flip-up shield 32. The first driving member 33 can provide power in any way, such as by a motor, cylinder, hydraulic cylinder, or magnetic attraction. Figure 2 shows the flip-up shield 32 in the state where it covers the first open end 10a1, and Figure 4 shows the flip-up shield 32 in the state where it avoids the first open end 10a1. Under the action of the first driving member 33, the flip-up shield 32 can switch between the two states.

[0090] For example, see Figures 1 and 2, where the number of flip-out shielding members 32 is one.

[0091] For example, the rotatable angle of the flip-up blocking member 32 is 90° to 130°. For example, the rotation angle of the flip-up blocking member 32 can be 90°, 93°, 95°, 98°, 100°, 103°, 105°, 108°, 110°, 113°, 115°, 118°, 120°, 122°, 125°, 128° or 130°, etc. The flip-up shield 32 has an arc-shaped cross-section perpendicular to its extension direction. The flip-up shield 32 extends along the first direction X. The central angle of the arc-shaped cross-section of the flip-up shield 32 is between 100° and 120°, and can be 90°, 93°, 95°, 98°, 100°, 103°, 105°, 108°, 110°, 113°, 115°, 118°, 120°, 122°, 125°, 128°, or 130°, etc. The central angle of the arc-shaped cross-section of the flip-up shield 32 is adapted to the rotatable angle of the flip-up shield 32. If the arc of the cross-section of the flip-up shield 32 is too large, it will occupy more installation space or may interfere with the movement trajectory of the cleaning component 20. If the arc of the cross-section of the flip-up shield 32 is too small, it may affect the shielding effect.

[0092] Referring to Figure 2, the flip-up shield 32 includes a main body 321 and a mounting part 322 fixedly connected, with a first driving member 33 drivingly connected to the mounting part 322. The main body 321 extends along a first direction X. When the cleaning component 20 is in a retracted state and the shield 30 covers the first open end 10a1, the main body 321 can catch easily falling objects from the cleaning component 20 below it. For example, the projection of the main body 321 along a third direction Z is greater than the projection of the cleaning component along a third direction Z, thereby improving the shielding effect and reducing the possibility of easily falling objects from the cleaning component 20 falling onto the walking surface.

[0093] For example, the shielding assembly 30 includes a first mounting base 31 disposed on the device body 10, and the flip shielding member 32 is rotatably disposed on the first mounting base 31.

[0094] In other embodiments not shown, the shielding assembly 30 includes two first mounting bases 31, both of which are disposed on the device body, and the two first mounting bases 31 are capable of supporting both ends of the flip-up shielding member 32 respectively. It is understood that in this embodiment, a second open end is not provided.

[0095] In some embodiments, referring to FIG2, the first receiving cavity 10a also has a second open end 10a2 that is open to the periphery of the device body 10. The shielding assembly 30 also includes a support 34 disposed on the side of the device body 10 near the second open end 10a2. The support 34 is left open at the second open end 10a2 to support the end of the flip shielding member 32 near the second open end 10a2.

[0096] The support base 34 can support the end of the flip-up shield 32 near the second open end 10a2, and the flip-up shield 32 can move along the support base 34 to improve the stability of the rotation of the flip-up shield 32.

[0097] Understandably, the support base 34 can avoid the second open end 10a2 so as not to interfere with the cleaning component 20 protruding from the second open end 10a2 to perform cleaning operations.

[0098] For example, the support base 34 forms a clearance space 34a to avoid the cleaning component, and communicates with the first receiving cavity 10a. When the cleaning component 20 is in the retracted state, the end of the cleaning component 20 near the second open end 10a2 is located in the clearance space 34a. In some embodiments, referring to FIG2, the first mounting base 31 is disposed at the end of the flip-up shield 32 away from the second open end 10a2, and the first driving member 33 is disposed on the first mounting base 31.

[0099] The first mounting base 31 is located at the end of the flip-up shield 32 near the second open end 10a2, which may interfere with the movement trajectory of the cleaning component 20 and increase the difficulty of structural space arrangement. The first driving component 33 is located on the first mounting base 31 at the end of the flip-up shield 32 away from the second open end 10a2, and does not occupy the space of the second open end 10a2, which facilitates structural space arrangement.

[0100] For example, the first drive member 33 has a first drive shaft, and the mounting portion 322 of the flip-up shield 32 is detachably connected to the first drive shaft so that the first drive shaft can drive the flip-up shield 32 to rotate.

[0101] In some embodiments, referring to FIG3, the shielding assembly 30 further includes a guide groove 37 and a guide block 38, one of which is disposed on the support base 34, and the other of which is disposed on the flip shielding member 32.

[0102] The guide groove 37 and guide block 38 enable the flip-up shield 32 to rotate along a preset trajectory, resulting in smoother rotation. For example, the guide groove 37 is disposed on the support base 34, and the guide block 38 is disposed on the flip-up shield 32. The support base 34 has a stop portion 341, which limits the upward movement of the guide block 38, thereby limiting the upward movement of the flip-up shield 32.

[0103] For example, the guide block 38 can rotate within a range of 90° to 130° along the rotation axis of the guide groove 37 relative to the flip-up shield 32, and can be 90°, 93°, 95°, 98°, 100°, 103°, 105°, 108°, 110°, 113°, 115°, 118°, 120°, 122°, 125°, 128°, or 130°, etc. The rotation axis is along the extension direction of the first drive shaft.

[0104] In some embodiments, referring to Figures 2 and 4, the cleaning device 100 further includes a detection component 60 for detecting whether the blocking component 30 is in a position that avoids the first open end 10a1 or is in a position that blocks the first open end 10a1.

[0105] The detection component 60 facilitates confirmation that the flip-up shield 32 has reached the preset position. During cleaning operations, this reduces the likelihood of the flip-up shield 32 colliding with the cleaning component 20 due to improper movement. When the first open end 10a1 needs to be shielded, it improves the shielding effect and reduces the possibility of poor shielding due to improper positioning of the flip-up shield 32. The detection component 60 can be a proximity switch or a limit switch.

[0106] For example, referring to Figure 4, the detection assembly 60 includes a detection element 61 and a light-shielding member 62, with one detection element 61 corresponding to one light-shielding member 62. The two light-shielding members 62 respectively detect whether the flip-up blocking member 32 has moved to a preset position upwards and downwards. For example, both light-shielding members 62 are disposed on the flip-up blocking member 32. One detection element 61 is disposed on the device body 10 and corresponds to one of the light-shielding members 62; the other detection element 61 is disposed on the support base 34 and corresponds to the other light-shielding member 62.

[0107] In some embodiments not shown, a light-shielding member and two detection elements 61 may also be provided. The two detection elements 61 are respectively disposed on the main body 10 of the device, corresponding to the position of the flip-up shielding member 32 in the shielding position and the position of the avoidance position.

[0108] In some embodiments, please refer to Figures 3 and 4. The shielding component 30 also includes a limiting member 39 disposed on the flip shielding member 32. When the flip shielding member 32 shields the first open end 10a1, the limiting member 39 abuts against the device body 10.

[0109] The limiting member 39 can limit the tilting shield 32. After the cleaning operation is completed, the cleaning assembly 20 moves into the first receiving cavity 10a. When the tilting shield 32 covers the first open end 10a1 below the cleaning assembly 20, the limiting member 39 can abut against the main body 10 of the equipment, restricting the tilting shield 32 from rotating further downward. For example, the limiting member 39 can be set at the middle position and / or both ends of the tilting shield 32 along the first direction X.

[0110] It is understandable that when the limiting member 39 abuts against the main body 10 of the device, the flip-blocking member 32 has already rotated to a position that can block the first open end 10a1, and the projection of the cleaning component 20 along the third direction Z is entirely located on the flip-blocking member 32.

[0111] For example, the limiting member 39 includes a soft material, such as a rubber pad, to cushion and reduce the possibility of the limiting member 39 being damaged by collision with the device body 10 or causing collision noise.

[0112] For example, referring to Figures 5-7, the shielding assembly 30 also includes a bearing 302, the first mounting base 31 has a mounting groove 31a, the connecting post 324 of the flip shield 32 is located in the mounting groove 31a, the connecting post 324 is detachably connected to the first drive shaft, and the bearing 302 is sleeved on the connecting post 324 and located in the mounting groove 31a to improve the smoothness of the rotation of the flip shield 32.

[0113] In some embodiments, please refer to Figures 8-9. The first mounting base 31 is disposed at the end of the flip-up shield 32 away from the second open end 10a2, and the first driving member 33 is disposed at the device body 10 near the second open end 10a2. The shielding assembly 30 also includes a driving gear 35 and a driving rack 36 that mesh with each other. The driving rack 36 is disposed at the end of the flip-up shield 32 near the second open end 10a2, and the driving gear 35 is connected to the first driving member 33.

[0114] By meshing the drive gear 35 and the drive rack 36, the stability of the rotation of the flip-up shield 32 can be improved.

[0115] For example, the first mounting base 31 is disposed on one side of the flip-up shield 32 along the second direction Y.

[0116] In some embodiments, referring to Figures 10-11, the number of flip-up blocking members 32 is two, and the two flip-up blocking members 32 rotate in opposite directions. Figure 10 shows the state where the flip-up blocking member 32 blocks the first open end 10a1, and Figure 11 shows the state where the flip-up blocking member 32 avoids the first open end 10a1. Under the action of the first driving member 33, the flip-up blocking member 32 can switch between the two states.

[0117] During cleaning operations, the two flip-up shields 32 can rotate upwards in opposite directions to avoid interfering with the first open end 10a1. After cleaning, the cleaning assembly 20 moves into the first receiving cavity 10a, and the two flip-up shields 32 can rotate to align below the cleaning assembly 20 to block the first open end 10a1, reducing the likelihood of loose objects falling onto the walking surface. This increases the covering area and improves the covering effect. The rotation axes of the two flip-up shields 32 can be coaxial.

[0118] It is understood that when the number of flip-up blocking members 32 in this embodiment is two, the rotatable angle of each flip-up blocking member can be set to 90° to 130°. For example, the rotation angle of each flip-up blocking member 32 can be 90°, 93°, 95°, 98°, 100°, 103°, 105°, 108°, 110°, 113°, 115°, 118°, 120°, 122°, 125°, 128°, or 130°, etc. The cross-section of each flip-up blocking member 32 perpendicular to the first direction X is arc-shaped. The central angle of the cross-section of each flip-up blocking member 32 is 90° to 130°. For example, the central angle of the arcuate cross section of each flip-out shield 32 can be 90°, 93°, 95°, 98°, 100°, 103°, 105°, 108°, 110°, 113°, 115°, 118°, 120°, 122°, 125°, 128° or 130°, etc.

[0119] In some embodiments, the rotation axes of the two flip-up blocking members 32 are spaced apart to allow space for the installation of the first drive member 33. Exemplarily, the first drive member 33 is positioned between the rotation axes of the two flip-up blocking members 32.

[0120] In some embodiments, when the two flip-up shields 32 cover the first open end 10a1, the adjacent ends of the two flip-up shields 32 overlap each other. For example, referring to Figures 12-13, at least one flip-up shield 32 has an extension 323. After the cleaning operation is completed, when the cleaning assembly 20 retracts into the first receiving cavity 10a and the two flip-up shields 32 can rotate to align below the cleaning assembly 20, at least a portion of the extension 323 can overlap with the other flip-up shield 32 along the third direction Z, reducing the possibility that loose material from the cleaning assembly 20 might leak out of the flip-up shields 32 due to gaps at the point where the two flip-up shields 32 align, thus contaminating the floor.

[0121] In some embodiments, please refer to Figures 12-13, the cleaning device 100 also includes a transmission assembly 40, through which the first drive member 33 is driven to be connected to two flip-up shield members 32.

[0122] The transmission method of the transmission component 40 is not limited; it can be achieved through gear transmission, chain transmission, belt transmission, or worm gear transmission, etc.

[0123] In some embodiments, referring to Figures 12-13, the transmission assembly 40 includes a first transmission tooth 41, a second transmission tooth 42, and an intermediate transmission tooth 43. The first transmission tooth 41 is connected to the first driving member 33; two flip-blocking members 32 are each connected to one of the second transmission teeth 42; one of the two second transmission teeth 42 meshes with the first transmission tooth 41 through the intermediate transmission tooth 43, and the other of the two second transmission teeth 42 directly meshes with the first transmission tooth 41.

[0124] Thus, the intermediate transmission gear 43 can drive the two second transmission gears 42 to rotate in opposite directions, thereby causing the two flipping blocking members 32 to rotate upward or downward from opposite directions respectively. The intermediate transmission gear 43 can be an idler gear.

[0125] Understandably, as an alternative embodiment, the transmission component in the above embodiments can also employ a drive gear and drive rack meshing transmission method. That is, the shielding component also includes two sets of meshing drive gears and drive racks, two first drive members are respectively disposed on the main body of the device, and two drive racks are respectively disposed at the end of the corresponding flip shield near the second open end, the two drive gears are respectively connected to the corresponding first drive members, and the two first drive members respectively drive one flip shield.

[0126] By meshing the drive gear and drive rack, the stability of the rotating shield can be improved. In some embodiments, please refer to Figures 14-15, the cleaning device 100 also includes a guide rail assembly 50 disposed on the device body 10, and the shield assembly 30 includes a curtain assembly 301, one end of which is fixedly disposed; the other end of the curtain assembly 301 can move along the guide rail assembly 50 so that the curtain assembly 301 shields or avoids the first open end 10a1.

[0127] The curtain assembly 301 moves along the guide rail 52, enabling the curtain assembly 301 to move along a preset trajectory to block or avoid the first open end 10a1.

[0128] When the cleaning equipment 100 is performing cleaning operations, the curtain assembly 301 can avoid the first open end 10a1 to prevent interference with the cleaning assembly 20's cleaning operations. After the cleaning operations are completed, the cleaning assembly 20 retracts into the first receiving cavity 10a, and the curtain assembly 301 can cover the first open end 10a1 below the cleaning assembly 20, reducing the possibility of easily falling objects on the cleaning assembly 20 falling onto the walking surface.

[0129] For example, in the above instance, the cleaning device 100 also includes a detection component to detect whether the curtain assembly has moved to a preset position. The detection component can be a proximity switch or a limit switch. The composition and setting of the detection component can be selected according to the actual situation, and will not be elaborated here.

[0130] In some embodiments, please refer to FIG15, the curtain assembly 301 includes a curtain 3011 and a guide rod 3015. One end of the curtain 3011 is fixed to the device body 10, and the other end of the curtain 3011 is connected to the guide rod 3015. The guide rod 3015 can move along the guide rail assembly 50 so that the curtain 3011 covers or avoids the first open end 10a1.

[0131] For example, the extension direction of the guide rail assembly 50 is parallel to the first direction X, and the extension direction of the guide rod 3015 is parallel to the second direction Y. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. Alternatively, the extension direction of the guide rail assembly 50 is parallel to the second direction Y, and the extension direction of the guide rod 3015 is parallel to the first direction X. Depending on the actual situation, in some embodiments, the first direction X may be referred to as longitudinal, and the second direction Y may be referred to as transverse.

[0132] For example, the curtain 3011 is made of a soft material and has an unfolded state and a retracted state. A guide rod 3015 is used to move the curtain 3011, and can be moved manually or by a power component. Driven by the guide rod 3015, the curtain 3011 can either cover or avoid the first open end 10a1. Specifically, when the cleaning equipment 100 is performing cleaning operations, one end of the curtain 3011 can move with the guide rod 3015 to put the curtain 3011 in the retracted state, allowing it to avoid the first open end 10a1 and thus avoid interfering with the cleaning assembly 20's cleaning operations. After the cleaning operation is completed, the cleaning component 20 retracts into the first receiving cavity 10a. One end of the curtain 3011 can move with the guide rod 3015 so that the curtain 3011 is in the unfolded state. The curtain 3011 can cover the first open end 10a1 from below, reducing the possibility of easily falling objects on the cleaning component 20 falling onto the walking surface.

[0133] For example, the curtain 3011 has an absorbent layer and a waterproof layer along the third direction Z. The absorbent layer can absorb liquid that falls on the cleaning components, and the waterproof layer is used to reduce the possibility of liquid penetrating the side of the curtain 3011 facing the walking surface and falling onto the walking surface.

[0134] For example, the absorbent layer can be made of materials such as cotton, linen, microfiber, bamboo fiber, or synthetic fiber. For example, the waterproof layer can be made of materials such as PVC (polyvinyl chloride) coated fabric, TPU (thermoplastic polyurethane) coated fabric, polyester fiber, or EVA (ethylene-vinyl acetate copolymer).

[0135] For example, the curtain 3011 can be configured as a rainproof cloth. The rainproof cloth has the characteristics of sun resistance, frost resistance, aging resistance, corrosion resistance, lightweight, easy folding and durability, which can improve the service life of the curtain 3011.

[0136] In some embodiments, referring to Figures 16 and 17, the shielding assembly 30 further includes a second driving member 3012, and one end of the guide rod 3015 is disposed on the second driving member 3012; the guide rail assembly 50 includes a guide tooth 51 and a guide rail 52 having a rack 521, the guide rail 52 is disposed on the device body 10, the second driving member 3012 is drivenly connected to the guide tooth 51, and the guide tooth 51 can mesh with the rack 521 for transmission.

[0137] For example, the extension direction of the guide rail 52 is parallel to the first direction X, and the extension direction of the guide rod 3015 is perpendicular to the first direction X. To facilitate understanding of the movement position of the second driving member 3012, Figure 17 shows two states: the second driving member 3012 is in a first position with the flip-up blocking member 32 blocking the first open end 10a1, and the second driving member 3012 is in a second position with the flip-up blocking member 32 avoiding the first open end 10a1.

[0138] The second driving component 3012 provides power for the movement of the guide rod 3015. The method of power supply for the second driving component 3012 is not limited; it can be driven by a motor, cylinder, hydraulic cylinder, magnetic attraction, etc. The meshing transmission between the guide tooth 51 and the rack 521 improves the efficiency of linear motion transmission, enhances the overall structural rigidity and stability, has low maintenance costs, and is easy to install and debug.

[0139] In some embodiments, please refer to Figures 17 and 18. The guide rail 52 includes a first guide rail 522 and a second guide rail 523 spaced apart on both sides of the first open end 10a1. The first guide rail 522 has a first guide groove 522a that can accommodate the movement of the guide tooth 51. The rack 521 is located in the first guide groove 522a. The second guide rail 523 has a second guide groove 523a that can accommodate the movement of the other end of the guide rod 3015.

[0140] The curtain 3011 is positioned between the first guide rail 522 and the second guide rail 523. One end of the guide rod 3015 is connected to the second driving member 3012, and the other end is located in the second guide groove 523a. The second driving member 3012 moves along the first guide groove 522a, and the guide rod 3015 moves along the second guide groove 523a. The second guide groove 523a guides the movement direction of the guide rod 3015 and also limits its movement, making the movement of the guide rod 3015 smoother and reducing the possibility of wrinkles or damage to the curtain 3011 caused by deviation of the guide rod 3015's movement trajectory.

[0141] In some embodiments, referring to Figures 17 and 18, the guide rail assembly 50 is arranged longitudinally along the first open end 10a1 so that the curtain assembly 301 can cover the first open end 10a1 longitudinally. The longitudinal direction of the first open end 10a1 is parallel to the first direction X. Exemplarily, the extension directions of the first guide rail 522 and the second guide rail 523 are both parallel to the first direction X. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0142] In other embodiments, referring to FIG19, the guide rail assembly 50 is arranged laterally along the first open end 10a1 so that the curtain assembly 301 can cover the first open end 10a1 laterally. The lateral direction of the first open end 10a1 is parallel to the second direction Y. Exemplarily, the extension directions of the first guide rail 522 and the second guide rail 523 are both parallel to the second direction Y.

[0143] In some embodiments, please refer to Figures 20 and 21. The curtain assembly 301 includes a roller blind 3013 and a rotating mechanism 3014. The rotating mechanism 3014 is disposed on the main body 10 of the device. One end of the roller blind 3013 is fixed to the rotating mechanism 3014, and the other end of the roller blind 3013 can move along the guide rail assembly 50 so that the roller blind 3013 covers or avoids the first open end 10a1.

[0144] The rotating mechanism 3014 provides power for the movement of the roller blind 3013. Exemplarily, the roller blind 3013 comprises a rigid material and is capable of being extended and retracted under the drive of the rotating mechanism 3014. Driven by the rotating mechanism 3014, the roller blind 3013 can either cover or avoid the first open end 10a1.

[0145] Specifically, when the cleaning equipment 100 needs to perform cleaning operations, under the action of the rotating mechanism 3014, the roller shutter 3013 gradually rolls onto the rotating mechanism 3014, so that the roller shutter 3013 is in a retracted state. The roller shutter 3013 can avoid the first open end 10a1 to avoid interfering with the cleaning component 20's cleaning operations. After the cleaning operation is completed, the cleaning component 20 moves into the first receiving cavity 10a. Under the action of the rotating mechanism 3014, the end of the roller shutter 3013 away from the rotating mechanism 3014 can move along the guide rail assembly 50, gradually moving away from the rotating mechanism 3014, so that the roller shutter 3013 is in an unfolded state. The roller shutter 3013 can cover the first open end 10a1 from below, reducing the possibility of easily falling objects on the cleaning component 20 falling onto the walking surface.

[0146] Exemplarily, the roller blind 3013, in its unfolded state, has an absorbent layer and a waterproof layer along the third direction Z. The absorbent layer can absorb liquids dropped from the cleaning components, and the waterproof layer reduces the possibility of liquids seeping out of the roller blind 3013 and falling onto the walking surface. Exemplarily, the absorbent layer can be made of materials such as cotton, linen, microfiber, bamboo fiber, or synthetic fiber. Exemplarily, the waterproof layer can be made of materials such as PVC (polyvinyl chloride), FRP (fiberglass reinforced plastic) coated fabric, or silicone.

[0147] For example, the roller shutter 3013 may include a metal sheet. The metal sheet is waterproof, can be made with a smaller thickness to reduce its footprint, has good durability, and can extend its service life.

[0148] Understandably, the rigidity of the roller blind 3013 is set such that, without the need for guide members to move the roller blind 3013 away from the end of the rotating mechanism 3014, it is sufficient to allow the roller blind 3013 to move along the guide rail assembly 50 without stacking up, and to be stored on the rotating mechanism 3014.

[0149] In some embodiments, referring to FIG21, the rotating mechanism 3014 includes a second mounting base 3141, a rotating shaft, and a third driving member 3142. The second mounting base 3141 is disposed on the device body 10; the rotating shaft is disposed on the second mounting base 3141, and one end of the roller blind 3013 is fixed to the rotating shaft; the third driving member 3142 is drivenly connected to the rotating shaft to drive the roller blind 3013 to move along the guide rail assembly 50, so that the roller blind 3013 is housed in the rotating shaft or released from the rotating shaft.

[0150] The second mounting base 3141 provides the mounting position for the rotating shaft, and the third driving component 3142 provides the power for the rotating shaft to rotate along the guide rail assembly 50, thereby driving the roller shutter 3013 to move along the guide rail assembly 50. The third driving component 3142 can be powered in any way, such as by a motor, cylinder, hydraulic cylinder, magnetic attraction, etc.

[0151] The pivot is used to move the roller blind 3013. Driven by the pivot, the roller blind 3013 can either cover or avoid the first open end 10a1. Specifically, when the cleaning equipment 100 is performing cleaning operations, under the action of the third drive member 3142, one end of the roller blind 3013 can move with the pivot, so that the roller blind 3013 is rolled onto the pivot and in a retracted state. The roller blind 3013 can avoid the first open end 10a1 to avoid interfering with the cleaning assembly 20's cleaning operations. After the cleaning operation is completed, one end of the roller blind 3013 can move with the pivot, so that the roller blind 3013 is released from the pivot and in an unfolded state. The cleaning assembly 20 retracts into the first receiving cavity 10a, and the roller blind 3013 can cover the first open end 10a1 below the cleaning assembly 20, reducing the possibility of easily falling objects on the cleaning assembly 20 falling onto the walking surface.

[0152] In other embodiments not shown, the rotating mechanism 3014 includes a second mounting base 3141, a rotating shaft, a third drive member 3142, and a fourth drive member. The second mounting base 3141 is disposed on the device body 10; the rotating shaft is disposed on the second mounting base 3141, and one end of the roller blind 3013 is fixed to the rotating shaft; the third drive member 3142 is drivenly connected to the rotating shaft to drive the roller blind 3013 to move along the guide rail assembly 50 so that the roller blind 3013 is housed in the rotating shaft; the fourth drive member is drivenly connected to the other end of the roller blind 3013 so that the other end of the roller blind 3013 is released from the rotating shaft.

[0153] Thus, the roller blind can be retracted into the pivot via the third drive member 3142 and released from the pivot via the fourth drive member, reducing the requirement for the hardness of the roller blind 3013 material and allowing for a wider range of material choices. For example, the roller blind 3013 can be made of a soft material. For example, the roller blind 3013 has an absorbent layer and a waterproof layer along the third direction Z. The absorbent layer can absorb liquids dropped from the cleaning components, and the waterproof layer reduces the possibility of liquids penetrating the roller blind 3013 and falling onto the walking surface. For example, the absorbent layer can be made of materials such as cotton, linen, microfiber, bamboo fiber, or synthetic fiber. For example, the waterproof layer can be made of materials such as PVC (polyvinyl chloride) coated fabric, TPU (thermoplastic polyurethane) coated fabric, polyester fiber, or EVA (ethylene-vinyl acetate copolymer).

[0154] For example, the pivot includes a pivot body and a sleeve, the sleeve being fitted onto the pivot, and the roller shutter 3013 can be housed in the sleeve or released from the pivot.

[0155] Understandably, in the above-described embodiment of the roller blind 3013 configuration, the guide rail assembly 50 can be arranged longitudinally along the first open end 10a1, so that the curtain assembly 301 can cover the first open end 10a1 longitudinally. The longitudinal direction of the first open end 10a1 is parallel to the first direction X. Alternatively, the guide rail assembly 50 can be arranged transversely along the first open end 10a1, so that the curtain assembly 301 can cover the first open end 10a1 transversely. The transverse direction of the first open end 10a1 is parallel to the second direction Y. The first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0156] Understandably, the aforementioned cleaning equipment for protecting curtains or roller blinds may also include a detection component for detecting the position of the curtain or roller blind to determine whether it is in a state of being blocked from or avoiding the first open end. The detection component can be a proximity switch or a limit switch. The specific composition and installation location of the detection component can be selected according to the actual situation, and will not be elaborated here.

[0157] It is understood that, in the above embodiments, the cleaning device 100 may further include a locking component. When the cleaning component 20 is in a stored state or an operating state, the position of the shielding component 30 can be locked. In corresponding embodiments, the locking component may be integrated into the first drive member, the second drive member, the third drive member, or the rotating mechanism; that is, the first drive member, the second drive member, the third drive member, or the rotating mechanism may all have a self-locking function, and the position of the shielding component 30 can be controlled to remain unchanged through the first drive member, the second drive member, the third drive member, or the rotating mechanism to achieve locking. Alternatively, the shielding component 30 may be locked by setting a separate mechanical structure or an electromechanical control locking component.

[0158] It is understood that the detection and locking components provided in the embodiments of this disclosure are applicable to various forms of occlusion components in different embodiments. Specific adaptations can be made according to the specific structure in each embodiment.

[0159] The following description uses several specific embodiments. These embodiments are not intended to be undue limitations on the technical solutions disclosed herein. In some cases, the various embodiments can be adapted to meet functional requirements.

[0160] Example 1

[0161] Please refer to Figures 1-7. The cleaning device 100 includes a device body 10, a cleaning component 20, and a shielding component 30. The device body 10 has a first receiving cavity 10a, which has a first open end 10a1 that opens towards the walking surface. The cleaning component 20 is disposed on the device body 10 and is movable relative to the device body 10. It has a retracted state that is contained within the first receiving cavity 10a and an operating state that at least partially protrudes from the first open end 10a1. The shielding component 30 is disposed on the device body 10 and is movable relative to the device body 10. When the cleaning component 20 is in the retracted state, the shielding component 30 can shield the first open end 10a1. When the cleaning component 20 is in the operating state, the shielding component 30 can avoid the first open end 10a1.

[0162] The shielding assembly 30 includes a first mounting base 31, a flip-up shielding member 32, and a first driving member 33. The first mounting base 31 is disposed on the main body 10 of the device; the flip-up shielding member 32 is rotatably disposed on the first mounting base 31; the first driving member 33 is drivenly connected to the flip-up shielding member 32 so that the flip-up shielding member 32 can rotate relative to the first mounting base 31 and can shield or avoid the first open end 10a1.

[0163] The number of flip-up blocking members 32 is one. The rotation angle of the flip-up blocking member 32 is 90° to 130°. The cross-section of the flip-up blocking member 32 perpendicular to the first direction X is arc-shaped. The central angle of the cross-section of the flip-up blocking member 32 is 90° to 130°.

[0164] The first receiving cavity 10a also has a second open end 10a2 that is open to the periphery of the device body 10. The shielding assembly 30 also includes a support 34, which is disposed on the device body 10 and located at the second open end 10a2 to support the flip shielding member 32 near the end of the second open end 10a2.

[0165] The first mounting base 31 is located at the end of the flip-up shield 32 away from the second open end 10a2, and the first driving member 33 is located at the first mounting base 31.
