[0036] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0037] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0038] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0039] like Figure 1 and Figure 2 As shown, this utility model provides a cleaning device capable of moving on a surface to be cleaned. The cleaning device moves forward in a forward direction and backward in a backward direction, with the overall movement direction being front-to-back. The cleaning device can be a cleaning robot, floor scrubber, window cleaner, or other cleaning equipment with wet cleaning components. The following description uses a cleaning robot as an example, but as can be seen from the above description, the scope of protection of this utility model is not limited thereto.

[0040] The cleaning equipment includes a main body (not shown in the figure), which includes at least a base (not shown in the figure), a bottom cover 200, and a cleaning component (wet cleaning component). The bottom cover 200 and the cleaning component are detachably mounted on the base.

[0041] The cleaning component can be a mop tray that rotates at high speed to clean the surface. Alternatively, the cleaning component can be a conveyor belt mop that moves back and forth via a conveyor belt to create reciprocating friction, mimicking the action of manually mopping the floor.

[0042] Considering that if the cleaning component touches a carpet during wet mopping, it may transfer wastewater and stains into the carpet fibers, the cleaning component is mounted on the main body of the device in a height-adjustable manner. This way, when it encounters a carpet, the cleaning component lifts upwards, effectively preventing wastewater and stains from being transferred onto the carpet.

[0043] Furthermore, the main body of the device is also provided with a shielding structure 100. In this embodiment of the present disclosure, by setting the shielding structure 100, the cleaning components can be shielded during the cleaning process, and the cleaning components can be isolated from the surface to be cleaned. This effectively prevents the cleaning equipment from contaminating the carpet or blanket that does not need to be cleaned during the cleaning process, thereby improving the cleaning effect of the cleaning equipment and the user experience.

[0044] The base and bottom cover 200 enclose an installation space, within which the shielding structure 100 is housed. This arrangement of the shielding structure 100 within the installation space not only avoids occupying additional installation space for the main body of the equipment but also isolates it from the external environment, preventing dirt from affecting its operation. When not in use, the shielding structure 100 is neatly concealed within the installation space, resulting in an aesthetically pleasing appearance.

[0045] Regarding saving installation space, the shielding structure 100 in this embodiment is more effective for cleaning equipment with a tracked mop. Due to its structural limitations, the tracked mop occupies more space in the vertical direction than a rotating mop disc. If the shielding structure 100 is placed on the outside of the main body of the equipment, the cleaning equipment will be larger in the vertical direction, which is not conducive to cleaning low areas (under sofas, under beds).

[0046] Regarding the installation position of the shielding structure 100, the shielding structure 100 can be installed on the bottom cover 200, so that the shielding structure 100 and the bottom cover 200 form a whole and can be detachably connected to the base. Alternatively, the shielding structure 100 can be installed on the base, with the bottom cover 200 covering the outer periphery of the shielding structure 100 and detachably connected to the base. Therefore, during assembly and disassembly, only the bottom cover 200 needs to be removed; there is no need to disassemble other structures on the main body of the equipment (such as the top cover, cleaning components, etc.), which has the advantage of convenient installation and maintenance.

[0047] In this embodiment of the invention, the main body of the device also includes a cleaning roller brush (dry cleaning component). The cleaning roller brush and the cleaning component can work together to clean. The cleaning roller brush is responsible for cleaning dry debris (dust, hair, and debris), and the cleaning component (mop tray) wet mops the surface to be cleaned.

[0048] like Figure 3 and Figure 4 As shown, the shielding structure 100 is located in the first area of ​​the main body of the device, and the first area is the auxiliary area. Figure 3 and attached Figure 4The shaded area is shown in the figure. The front boundary A of the first area in the direction of travel is the side of the cleaning roller brush near the front of the main body of the equipment, and the rear boundary B of the first area in the direction of travel is the side of the cleaning component near the rear of the main body of the equipment. In this way, it is not only beneficial for the shielding structure 100 to shield the cleaning component, but also will not affect the installation of the impact plate assembly (not shown) and circuit board on the front of the cleaning equipment. It can also make the weight distribution of the cleaning equipment more balanced, prevent the front or rear of the cleaning equipment from being too heavy, and ensure the stable operation of the cleaning equipment.

[0049] Regarding the front boundary A, the bottom cover 200 is provided with a first clearance opening 210 that cooperates with the cleaning roller brush. The front boundary A can also be the first clearance opening 210 extending along the axis of the cleaning roller brush and close to the edge of the front of the cleaning device.

[0050] Regarding the rear boundary B, as follows: Figure 3 As shown, when the cleaning component is a tracked mop or a roller-shaped cleaning element, the rear boundary B is either the edge of the tracked mop near the rear of the cleaning device, or the edge of the roller-shaped cleaning element near the rear of the cleaning device. The tracked mop or roller-shaped cleaning element is an attachment... Figure 3 The rectangular shape C within the first region.

[0051] like Figure 4 As shown, when the cleaning component is a mop tray, the rear boundary B is a hypothetical line passing through the endpoint B1 of the mop tray near the rear of the cleaning device and parallel to the axis of the cleaning roller brush. The mop tray is an attached... Figure 4 Two circular figures D within the first region.

[0052] In the embodiments disclosed herein, such as Figure 2 As shown, the shielding structure 100 includes at least a shielding member 140 that is movable relative to the main body of the device. The shielding member 140 has at least an initial position and a shielding position. An opening 300 is provided between the base and the bottom cover 200 in the direction of travel, facing the cleaning assembly. The opening 300 serves as a connection between the installation space and the external environment, and the shielding member 140 can be moved into or out of the installation space through the opening 300. The opening extends along the axial direction of the cleaning roller brush.

[0053] In this embodiment, the shield 140 moves within the area between the side of the cleaning roller brush near the rear of the device body and the side of the cleaning assembly near the rear of the device body. In the initial position, as... Figure 5As shown, the shielding member 140 is housed within the installation space. In the shielding position, the shielding member 140 extends beyond the installation space, and its projection in the vertical direction at least partially overlaps with the vertical projection of the cleaning component. Preferably, when the shielding member 140 is in the shielding position, its vertical projection overlaps with the vertical projection of the cleaning component, and the shielding member 140 completely covers the cleaning component. At this time, the shielding member 140 moves to the side of the cleaning component near the rear of the device body. It is worth noting that the shielding member 140 also has other positions besides the initial position and the shielding position.

[0054] In this embodiment, when the shielding member 140 is in its initial position, it is housed within the mounting space between the base and the bottom cover 200, and the cleaning components are not obstructed by the shielding member 140, allowing them to perform the cleaning task. At this time, as... Figure 5 As shown, the projections of the shielding member 140 in the vertical direction do not overlap with the projections of the cleaning component in the vertical direction; however, the projection of the shielding member 140 in the travel direction at least partially overlaps with the projection of the cleaning component in the travel direction, for example, the height range of the shielding member 140 is within the height range of the cleaning component. The above-described arrangement of the shielding member 140 and the cleaning component makes full use of the space in the vertical direction of the cleaning equipment.

[0055] When the blocking member 140 is in the blocking position, the cleaning component is in a raised state (moving upwards, away from the surface to be cleaned). At this time, the projection of the blocking member 140 in the traveling direction (horizontal direction) does not overlap with the projection of the cleaning component in the traveling direction. The blocking member 140 is located in the space between the raised cleaning component and the surface to be cleaned, and the projection of the cleaning component in the vertical direction is within the vertical projection of the blocking member 140. The blocking members 140 are distributed in the space between the raised cleaning component and the surface to be cleaned, achieving blocking of the cleaning component from below. This distribution of the blocking members 140 does not occupy the remaining space of the main body of the equipment, resulting in high space utilization.

[0056] When the shielding member 140 is in the shielding position, it is positioned between the surface to be cleaned and the cleaning component, isolating the cleaning component and preventing it from directly contacting the carpet or rug to be cleaned. This avoids contamination of the carpet or rug, effectively improving the applicability of the cleaning equipment and enhancing the user experience. Alternatively, when the shielding member 140 is in the shielding position, the cleaning component can contact the shielding member 140; or, a preset gap can exist between the cleaning component and the shielding member 140 in the vertical direction.

[0057] In this embodiment, the shield 140 is made of a flexible or rollable material. When the shield 140 is in its initial position, it is located between the sweeping roller brush and the cleaning assembly, where "between the sweeping roller brush and the cleaning assembly" refers to the distance between them in the direction of travel.

[0058] Preferably, the shielding member 140 is housed in the installation space in a rolled manner. Compared with the unrolled manner, the rolled manner can greatly reduce the space occupied by the shielding member 140, making the shielding structure 100 more compact. Moreover, the rolled shielding member 140 is not only applicable to tracked cleaning components, but also to other types of cleaning components, such as roller cleaning components and disc cleaning components. It is not affected by the shape of the cleaning component and can shield various types of cloths, thus having good versatility.

[0059] Specifically, the blocking member 140 has a winding state and an unwinding state. The winding and unwinding operations of the blocking member 140 can be performed manually by the user or by the drive mechanism 130. The following description uses the winding and unwinding operations of the blocking member 140 performed by the drive mechanism 130 as an example.

[0060] The drive mechanism 130 is used to switch the blocking member 140 between a winding state and an unwinding state. In the initial position, the blocking member 140 is in the winding state. In all positions other than the initial position (including the blocking position), the blocking member 140 is in the unwinding state, only to varying degrees. That is, in the unwinding state, the blocking member 140 has a blocking position, and when the blocking member 140 is in the blocking position, the projections of the blocking member 140 in the vertical direction at least partially overlap with the projections of the cleaning component in the vertical direction.

[0061] like Figure 6 As shown, the shielding member 140 includes at least a waterproof layer 141. When the shielding member 140 is in the shielded position, the waterproof layer 141 prevents liquid on the cleaning components from seeping through the shielding member 140 to the surface to be cleaned below. Of course, the shielding member 140 can also be made of a waterproof material, thus eliminating the need for a waterproof layer 141 on the shielding member 140.

[0062] In this embodiment, the shielding structure 100 further includes a rotatable scroll 110 disposed on the bottom cover 200 or the base, and a support arm 120 disposed on the bottom cover 200 or the base and capable of linear reciprocating motion in the direction of travel. One end of the shielding member 140 is disposed on the scroll 110, and the other end is disposed on the end of the support arm 120 near the cleaning component. The shielding member 140 is fastened to the scroll 110, which is used to wind or unwind the shielding member 140. The scroll 110 and the support arm 120 are perpendicularly distributed and perpendicular to the direction of travel.

[0063] The movement of the spool 110 and the support arm 120 can be achieved by a force applied by the user or by a force applied by the drive mechanism 130. The spool 110 and the support arm 120 are linked in response to the force applied by the user or the force applied by the drive mechanism 130.

[0064] Preferably, the movement of the spool 110 and the support arm 120 is achieved through the drive mechanism 130, that is, the spool 110 and the support arm 120 are respectively connected to the drive mechanism 130 for transmission. Furthermore, the spool 110 and the support arm 120 are driven by the same drive mechanism 130, which can reduce the number of drives, simplify the structure, and reduce production costs.

[0065] The drive mechanism 130 includes a motor 131 and a gearbox 132 mounted on the base or bottom cover 200. The support arm 120 is a rack extending in the direction of travel. Preferably, there is a pair of racks, which provides more stable and reliable support for the shielding member 140.

[0066] The shielding structure 100 also includes a first gear 150 that meshes with a rack and a second gear disposed on a spool 110. The first gear 150 and the second gear mesh with gears in the gearbox 132, respectively. For example, the transmission end of the gearbox 132 has a first output gear (not shown) and a second output gear (not shown). The first gear 150 meshes with the first output gear, and the second gear meshes with the second output gear.

[0067] Considering that a pair of racks are provided, a pair of first gears 150 are also provided. The pair of first gears 150 are mounted on the connecting shaft 160 and located at opposite ends of the connecting shaft 160, which is mounted on the bottom cover 200 or the base via a seat 161. The pair of first gears 150 includes a first driving gear located at one end of the connecting shaft 160 and meshing with the first output gear, and a first driven gear located at the other end of the connecting shaft 160. The connecting shaft 160 is parallel to the reel 110 and located in front of the reel 110.

[0068] The spool 110 is positioned near or at the opening to maximize space utilization. "The spool 110 is positioned near the opening" means that there is a gap of less than 10mm between the spool 110 and the opening in the direction of travel. The gap can range from 1 to 10mm. The gap can be 3mm, 5mm, 8mm, 10mm, etc., or it can be an increment between 1 and 10mm in increments of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, and 9mm.

[0069] In this embodiment, the main body of the device further includes a pair of drive wheels (not shown), and a support arm 120 is installed between the drive wheels and the cleaning roller brush. The projections of the support arm, the drive wheels, and the cleaning roller brush in the vertical direction do not overlap. The "between" refers to the area between the drive wheels and the cleaning roller brush along their rotation axis. The bottom cover has a second clearance opening 220 for avoiding the drive wheels. When the support arm 120 is mounted on the bottom cover, it is located between the first clearance opening 210 and the second clearance opening 220.

[0070] The aforementioned arrangement of the support arm 120 fully utilizes the space between existing functional components on the main body of the equipment, achieving the installation of the support arm 120 without additionally increasing the volume of the main body, resulting in high space utilization. Since the support arm 120 does not extend beyond the aforementioned first area when moving along the travel direction, there is no need to increase the outer diameter of the main body, ensuring the structural compactness of the main body in the horizontal direction. Furthermore, since the shielding structure 100 is located within the installation space between the bottom cover 200 and the base, it does not occupy additional external space of the main body, ensuring the structural compactness of the main body in the vertical direction.

[0071] In this embodiment of the disclosure, the shielding structure 100 further includes a guide unit for guiding the movement of the support arm 120, the guide unit being distributed along the movement direction of the support arm 120. The guide unit is distributed between the drive wheel and the cleaning roller brush, wherein the projections of the guide unit in the vertical direction, the projections of the drive wheel in the vertical direction, and the projections of the cleaning roller brush in the vertical direction do not overlap.

[0072] In one embodiment, the guide unit includes a linear guide rail and a slider disposed on the base or bottom cover 200, and the support arm 120 is disposed on the base or bottom cover 200 via the linear guide rail.

[0073] In another embodiment, the guide unit includes a cooperating guide rib and a guide groove, one of which is disposed on the base or the bottom cover 200, and the other is disposed on the support arm 120.

[0074] In this embodiment, a support rod 170 is provided on the end of the support arm 120 near the cleaning component. The support rod 170 is distributed perpendicular to the direction of travel and is used to support the shielding member 140. One end of the shielding member 140 is provided on the reel 110, and the other end is provided on the support rod 170. Alternatively, one end of the shielding member 140 can be provided on the reel 110, and the other end can be provided on both the support rod 170 and the support arm 120. It is understood that when the shielding member 140 is connected to the support arm 120, it is only connected to the end of the support arm 120 near the cleaning component.

[0075] The dimension of the support rod 170 perpendicular to the direction of travel is larger than the dimension of the blocking member 140 in the direction of travel. The blocking member 140 is fastened to the support rod 170, which can be a detachable connection (e.g., snap-fit) or a fixed connection (e.g., adhesive).

[0076] This utility model also provides a cleaning system, which includes cleaning equipment and a base station capable of interfacing with the cleaning equipment. The specific structure of the cleaning equipment is described in the above embodiments. Since this cleaning equipment employs all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0077] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
