[0028] The following describes embodiments of the present disclosure with reference to the accompanying drawings. For ease of understanding, the elements shown in the drawings may include elements whose sizes and scales are different from the actual sizes and scales.

[0029] In the specific embodiments of the present disclosure, "front (front side)", "rear (rear side)", "left (left side)", "right (right side)", "up (upper side)", and "down (lower side)" are all relative to the working state of the intelligent cleaning device according to the present disclosure. Specifically, "front (front side)", "rear (rear side)" refer to the front and rear sides of the intelligent cleaning device according to the present disclosure in the normal forward direction when the intelligent cleaning device is in normal working state on the surface to be cleaned, "left (left side)", "right (right side)" refer to the left and right sides when viewed from the front side in the normal forward direction, and "up (upper side)", "down (lower side)" refer to the upper and lower sides in the height direction perpendicular to the surface to be cleaned when the intelligent cleaning device according to the present disclosure is in normal working state on the surface to be cleaned. Here, "normal working state" refers to the state of the intelligent cleaning device when it is normally performing its cleaning task, which is distinguished from abnormal states such as retreat and swinging of the intelligent cleaning device in the escape mode. The intelligent cleaning device according to the present disclosure can move autonomously according to a preset control scheme, and perform effective cleaning operations on the surface to be cleaned during autonomous movement. The surface to be cleaned can be a plane or a curved surface with a large radius of curvature, typically the floor of each room in a building. In addition, cleaning operations include but are not limited to sweeping, mopping, and vacuuming.

[0030] The following combination Figures 1 to 7 The structure of the cleaning system according to the first embodiment of the present disclosure will be described.

[0031] Figure 1 is a schematic diagram of the cleaning system 30, wherein some parts are omitted.

[0032] The cleaning system 30 may include an intelligent cleaning device 32 and a charging station 34. Figure 1 As shown, the smart cleaning device 32 can be parked at a charging station 34, and the charging station 34 can supply power to the smart cleaning device 32. When it is necessary to clean the surface to be cleaned, the smart cleaning device 32 can leave the charging station 34 to autonomously perform a preset cleaning task.

[0033] Figure 2 and Figure 3 is a schematic diagram of the intelligent cleaning device 32.

[0034] The intelligent cleaning device 32 may include a housing 36, a water tank 42, and a dust box 44. The housing 36 may be roughly disc-shaped, and the rear portion of the housing 36 may be provided with an opening 40 that opens to the rear side. The water tank 42 is used to contain cleaning liquid, such as water or a mixed solution of water and detergent; the dust box 44 is used to collect dust. In some embodiments, the water tank 42 and the dust box 44 may be integrated together to form a container 38, for example, a portion of the water tank 42 and a portion of the dust box 44 may be integrally formed. Figure 2As shown, the container 38 can be inserted into and placed on the housing 36 through the opening 40, and the water tank 42 can include an outer portion 46 extending rearward from the housing 36. The housing 36 and the outer portion 46 can be combined to form a substantially oval shape in a top view, so that the area of ​​the rear of the water tank 42 in a top view is larger than the area of ​​the rear of the housing 36 in a top view, which enables the intelligent cleaning device 32 to have a larger water capacity than a water tank that matches the rear shape of the housing 36. Figure 3 As shown, container 38 can exit housing 36 via opening 40, thereby refilling water tank 42. Some intelligent cleaning devices 32 may only have a water tank 42 without a dust box 44, such as an intelligent floor scrubber with a single mopping function. In this case, container 38 only includes water tank 42. In some embodiments, housing 36 may have other shapes, such as an oval or square. In this case, water tank 42 still has an outer portion 46 that extends beyond the rear side of housing 36 and toward the rear of housing 36. When viewed from above, the rear area of ​​water tank 42 is still larger than the rear area of ​​housing 36 when viewed from above.

[0035] Figure 4 It is a partial enlarged view of the housing 36.

[0036] The shell 36 may be provided with a recess 48, a first guide surface 49, and a plurality of charging pieces 50. The recess 48 may be provided on the inner side wall of the opening 40 and be recessed inwardly toward the upper side of the interior of the shell 36. The first guide surface 49 may be provided at the intersection of the inner side wall of the opening 40 and the outer peripheral surface of the shell 36, and be oriented toward the rear side and the lower side at the same time. The recess 48 and the first guide surface 49 may be provided at approximately the same position in the circumferential direction C of the shell 36 and have approximately the same circumferential width. The charging piece 50 may be provided on the outer periphery of the shell 36 and be located above the opening 40. In other words, when the container 38 is placed on the shell 36, the charging piece 50 may be located on the outer side 46 of the water tank 42 (see Figure 2 ) on the upper side. Multiple charging sheets 50 can be arranged side by side in the circumferential direction of the housing 36. For example, two charging sheets 50 can be arranged bilaterally symmetrically. A battery can be placed inside the housing 36, and the charging sheet 50 is electrically connected to the battery.

[0037] Figure 5 is a schematic diagram of a charging station 34 .

[0038] The charging station 34 may include a plurality of charging arms 74 , and a charging contact 76 may be provided at a free end of each charging arm 74 .

[0039] Figure 6 It is a partially enlarged view of the cleaning system 30 , in which the smart cleaning device 32 is parked at the charging station 34 .

[0040] The smart cleaning device 32 can move backward from a predetermined position outside the charging post 34, so that the charging piece 50 approaches the charging contact 76 at the front end of the charging arm 74. During the movement of the charging piece 50 toward the charging contact 76, the upper surface of the outer portion 46 of the water tank 42 can abut against the lower surface of the charging arm 74, so that the outer portion 46 can support the charging arm 74 from the bottom, thereby preventing the charging arm 74 from vibrating in the vertical direction due to the vibration caused by the smart cleaning device 32 contacting the charging post 34, thereby avoiding the problem of the charging arm 74 being difficult to align with the charging piece 50 in the vibrating state, and also preventing the charging arm 74 from being hit by the retreating smart cleaning device 32 in the vibrating state and being damaged by the smart cleaning device 32 and the charging arm 74.

[0041] The smart cleaning device 32 can continue to retreat until the charging piece 50 is as shown in FIG. Figure 6 As shown, the outer portion 46 rests against the charging contacts 76 at the front end of the charging arm 74. The charging sheet 50 resting against the charging contacts 76 can make electrical contact with the charging contacts 76, so that the charging station 34 can supply power to the intelligent cleaning device 32. At the same time, the upper surface of the outer portion 46 can continue to contact the lower surface of the charging arm 74, so that the outer portion 46 maintains support for the charging arm 74.

[0042] Figure 7 It is an exploded view of the water tank 42.

[0043] The water tank 42 may include a accommodating chamber 52, a cover plate 54, and a plug 56. The cover plate 54 may close the upper opening of the accommodating chamber 52 and be sealed to the wall of the accommodating chamber 52. The cover plate 54 may be provided with a water injection hole 58, and the plug 56 may be mounted on the cover plate 54 to block the water injection hole 58. When it is necessary to refill the water tank 42 with water, the plug 56 may be removed from the water injection hole 58, and water may be injected into the accommodating chamber 52 through the water injection hole 58. After refilling, the plug 56 may be resealed in the water injection hole 58. The plug 56 may be at least partially made of an elastic material, such as rubber or silicone. In this way, the plug 56 may be sealed to the cover plate 54 through its own elastic deformation. When the container 38 is placed on the housing 36, the entire plug 56 may be housed within the housing 36.

[0044] In other embodiments, the plug 56 may also be located entirely or partially on the outer portion 46 (see FIG. Figure 2 ).

[0045] It will be appreciated that by housing at least a portion of plug 56 within housing 36, plug 56 is protected and constrained by housing 36, making it less likely to be damaged or fall out. Furthermore, because at least a portion of plug 56 is shielded by housing 36, plug 56 can only be opened when container 38 is separated from housing 36, thereby preventing charging sheet 50 from coming into contact with water during the water replenishment process.

[0046] The intelligent cleaning device 32 may further include a locking element 47. The locking element 47 can be switched between a locked position and an unlocked position. In the locked position, the locking element 47 can lock the container 38 to the housing 36. In the unlocked position, the locking element 47 can allow the container 38 to be separated from the housing 36. The locking element 47 can be mounted on the water tank 42. When the container 38 is placed on the housing 36, a portion of the locking element 47 can be located on the outer portion 46, while another portion of the locking element 47 can be stored inside the housing 36.

[0047] In other embodiments, the locking element 47 may also be completely located on the outer side 46 .

[0048] It can be understood that by arranging at least a portion of the locking element 47 on the outer portion 46, the locking element 47 does not occupy too much space inside the housing 36, thereby saving the internal space of the housing 36. In addition, compared with being arranged at other positions, the locking element 47 arranged on the outer portion 46 can be easily operated, for example, pressed, making the intelligent cleaning device 32 easy to use.

[0049] The upper portion of the water tank 42 may be provided with a downwardly recessed mounting groove 60. The locking element 47 may be at least partially retained within the mounting groove 60 and may slide up and down under the guidance of the mounting groove 60, thereby enabling the locking element 47 to switch between an upper locked position and a lower unlocked position. Sliders 62 may be provided on the left and right sides of the locking element 47, respectively. The slides 62 may be received by slide grooves 64 provided on the sidewalls of the mounting groove 60. A limit portion 66 may be provided at the upper end of the slide groove 64. The limit portion 66 may block the rising slide 62 to confine the majority of the locking element 47 within the mounting groove 60, thereby preventing the locking element 47 from separating from the water tank 42.

[0050] The intelligent cleaning device 32 may further include a spring 68. The spring 68 may be disposed between the locking element 47 and the bottom surface of the mounting slot 60 and configured to bias the locking element 47 toward the locked position. In this configuration, the locking element 47 can be driven by the spring 68 to return from the unlocked position to the locked position.

[0051] The locking element 47 may be provided with a convex portion 70 that protrudes upward. When the container 38 is placed on the housing 36 and the locking element 47 is in the locked position, the convex portion 70 may extend from the mounting groove 60 and into the recess 48 (see FIG. Figure 4 ), that is, extending from the water tank 42, thereby locking the container 38 on the housing 36. When the locking element 47 is in the unlocked position, the entire protrusion 70 can be received in the mounting groove 60, that is, received in the water tank 42, so that the container 38 can be freely removed from and inserted into the housing 36.

[0052] In other embodiments, the locking element 47 may also lock the container 38 on the housing 36 in other ways. For example, the locking element 47 may be hooked or clamped to the container 38 .

[0053] In other embodiments, the mounting groove 60 may also be provided at the lower portion of the water tank 42 and recessed upward, and the positions of the recess 48 and the protrusion 70 may be adjusted accordingly. In this configuration, the locked position may be a lower position, and the unlocked position may be an upper position.

[0054] The protrusion 70 may include a second guide surface 72. The second guide surface 72 may be oriented toward the front side while being oriented toward the upper side. During the insertion of the container 38 into the housing 36, the second guide surface 72 may abut against the first guide surface 49 (see FIG. Figure 4 ), so that the second guide surface 72 can move downward under the guidance and pressure of the first guide surface 49, thereby prompting the locking element 47 to move from the locked position to the unlocked position.

[0055] In other embodiments, the intelligent cleaning device 32 may be provided with only one of the first guide surface 49 and the second guide surface 72 .

[0056] It can be understood that by providing the first guide surface 49 and / or the second guide surface 72, the first guide surface 49 and the second guide surface 72 can convert the force used to drive the container 38 into a force used to drive the locking element 47. In this way, when inserting the container 38 into the housing 36, the locking element 47 does not need to be additionally operated, thereby further improving the ease of use of the intelligent cleaning device 32.

[0057] The following combination Figure 8 and Figure 9 The structure of the cleaning system according to the second embodiment of the present disclosure is described. The second embodiment is a modification of the first embodiment. For features identical or similar to those of the first embodiment, the same reference numerals are used in this embodiment and redundant description of these features is omitted.

[0058] Figure 8 is a schematic diagram of an intelligent cleaning device 32 .

[0059] Compared to the first embodiment, the smart cleaning device 32 may further include at least one guide groove 78. The guide groove 78 may be provided on the upper surface of the outer portion 46, that is, on the cover plate 54. Preferably, the smart cleaning device 32 may include multiple guide grooves 78, each of which may correspond to a charging piece 50.

[0060] Figure 9 is a schematic diagram of the container 38.

[0061] The guide groove 78 may include an open end 80, a closed end 82, and a bottom surface 84. The open end 80 may be open toward the rear side of the water tank 42, and the bottom surface 84 may extend forward from the open end 80 to the closed end 82. The closed end 82 may be located below the charging blade 50, for example, the closed end 82 may be substantially flush with the charging blade 50. During the movement of the charging blade 50 toward the charging contacts 76 of the charging arm 74, the charging arm 74 may extend into the guide groove through the open end 80 and rest against the bottom surface 84.

[0062] It will be appreciated that the guide groove 78 can accommodate, support, and guide the charging arm 74 as the charging piece 50 moves toward the charging contacts 76 of the charging arm 74, allowing the charging piece 50 to more accurately dock with the charging contacts 76. Furthermore, the guide groove 78 can prevent the intelligent cleaning device 32 from colliding with the charging arm 74 during the backward movement, thereby preventing damage to the intelligent cleaning device 32 and the charging arm 74.

[0063] In other embodiments, the width of the guide groove 78 in the left-right direction may gradually increase from the front side to the rear side (the side away from the charging sheet 50 ), so that the charging arm 74 can enter the guide groove 78 more easily.

[0064] In other embodiments, the bottom surface 84 may be formed with a slope that slopes from front to back, that is, from the closed end 82 to the open end 80. In other words, in the vertical direction, the bottom surface 84 is located at a lower position at the open end 80 than at the closed end 82. On the one hand, the bottom surface 84 allows the charging arm 74 to enter the guide groove 78 more easily. On the other hand, the bottom surface 84 can collect liquid that enters the guide groove 78 (for example, water accidentally splashed into the guide groove 78 during the water replenishment process) to the open end 80, allowing the liquid to exit the guide groove 78 through the open end 80, thereby preventing the liquid from being retained in the housing 36 or the guide groove 78.

[0065] It should be understood that the above embodiments are merely exemplary and are not intended to limit the present disclosure. Those skilled in the art may make various modifications and changes to the above embodiments based on the teachings of the present disclosure without departing from the scope of the present disclosure.
