Description

Technical Field

[0001] This disclosure relates to the field of smart home technology, and more specifically, to a base station and cleaning system. Background Technology

[0002] As society continues to develop and people's living standards improve, floor scrubbers are becoming increasingly popular in households because they are more time-saving and labor-saving than traditional manual cleaning. A typical floor scrubber consists of the main unit and a cleaning base. The cleaning base includes a cleaning head that rotates at high speed to scrub the floor.

[0003] Typically, cleaning equipment needs to be used in conjunction with a dedicated base station, which can be docked to park the floor scrubber. However, docking a common base station with a floor scrubber is rather inconvenient.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0063] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0065] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” etc. are used only as markers and are not a limitation on the number of objects.

[0066] Embodiments of this disclosure provide a cleaning system, such as Figure 1 As shown, the cleaning system includes cleaning equipment and a base station 20. The cleaning equipment can be, for example, a handheld floor scrubber, a handheld vacuum cleaner, or a robotic vacuum cleaner. The base station 20 is used to dock with the cleaning equipment, i.e., to park the cleaning equipment. The cleaning equipment can perform functions such as docking, charging, self-cleaning, sewage discharge, and water replenishment on the base station 20. Below, the embodiments of this disclosure will be described in detail using a cleaning system including a handheld floor scrubber and a base station 20 as an example.

[0067] Specifically, the handheld floor scrubber includes a main body and a cleaning base 10, with the cleaning base 10 connected to one end of the main body. The main body is equipped with a handle assembly, which is connected to the end of the main body away from the cleaning base 10, for the user to operate and hold. By holding the handle assembly, the user can control the cleaning base 10 to move on the surface to be cleaned, thereby achieving the cleaning purpose of the surface to be cleaned.

[0068] The cleaning base 10 is movably connected to the device body, for example, by pivoting or ball joint connection. When the user holds the handle assembly to move the cleaning base 10 on the surface to be cleaned, the relative angle between the device body and the cleaning base 10 can be adjusted by moving the cleaning base 10 and the device body, thereby changing the operating angle and flexibly adjusting the cleaning posture for easier cleaning operation.

[0069] Specifically, such as Figure 2 and Figure 3 As shown, the cleaning base 10 includes a base body 110 and a cleaning head 130 disposed on the base body 110. The cleaning head 130 performs cleaning operations on the surface to be cleaned. The cleaning head 130 can be, for example, a cleaning roller, and the number of cleaning rollers can be, for example, one, two or more. The cleaning roller can rotate at high speed to mop the floor. The cleaning roller can consist of a rotating shaft and a cleaning cloth wrapped around the surface of the rotating shaft. The rotating shaft rotates at high speed under a drive to drive the cleaning surface to rotate at a high speed, thereby performing high-speed rotational friction cleaning on the surface to be cleaned. The cleaning cloth can be detachably connected to the rotating shaft, which facilitates the replacement of the cleaning cloth and improves the maintenance economy of the cleaning roller. Of course, the cleaning head 130 can also be a tray, and the cleaning operation on the surface to be cleaned is performed by rotating the tray.

[0070] Among them, such as Figure 2 and Figure 3 As shown, the bottom of the base body 110 is equipped with an assist wheel 140. The assist wheel 140 is positioned along the length of the bottom of the cleaning base 10 on the side away from the cleaning roller. The roller of the assist wheel 140 can be arranged parallel to the rotation axis of the cleaning roller. The assist wheel 140 assists in moving the cleaning base 10 on the surface to be cleaned when the user operates it. The assist wheel 140 can be an active assist wheel with a power source, meaning that when the cleaning base 10 needs to move, the power source drives the assist wheel 140 to rotate, thereby assisting the user in operating the handheld floor scrubber and improving the user experience. Alternatively, the assist wheel 140 can be an unpowered assist wheel, assisting the user in moving the cleaning base 10 when pushing it.

[0071] Specifically, such as Figure 2 and Figure 3 As shown, the base body 110 is also equipped with a liquid supply tank 120. When the cleaning roller and / or the ground need to be wetted during the movement of the cleaning base 10, the liquid supply tank 120 supplies cleaning fluid. By placing the liquid supply tank 120 on the cleaning base 10, the weight of the cleaning base 10 can be increased, thereby allowing the cleaning base 10 to apply greater pressure to the ground on the cleaning roller, thus increasing the friction between the cleaning roller and the surface to be cleaned, ultimately improving the cleaning effect. The cleaning fluid in the liquid supply tank 120 can be water or a solution of water and cleaning agent. The liquid supply tank 120 may also have multiple storage chambers to store different cleaning fluids; for example, one storage chamber may store cleaning agent, and another may store clean water.

[0072] In some embodiments, the handheld cleaning device can move along the forward direction (first direction X) via the ramp 230 to the base station 20 to perform at least one function such as docking, charging, self-cleaning, sewage discharge, and water replenishment on the base station 20. Along the forward direction of the handheld cleaning device, the liquid supply tank 120 is at a distance from the rear side of the base body 110; that is, along the forward direction of the handheld cleaning device, the center of gravity of the liquid supply tank 120 is located on the side of the base body 110 closer to the cleaning head 130. The forward shift of the center of gravity of the cleaning base 10 allows more of the weight of the liquid supply tank 120 to be applied to the cleaning head 130, thereby increasing the pressure on the ground of the cleaning head 130 located in front of the cleaning base 10. This, in turn, increases the friction between the cleaning head 130 and the surface to be cleaned, thus improving the cleaning effect.

[0073] In this case, along the forward direction of the handheld cleaning device, the distance between the center of gravity of the liquid supply tank 120 and the front side of the base body 110 is less than the distance between the center of gravity of the liquid supply tank 120 and the rear side of the base body 110. That is, the center of gravity of the liquid supply tank 120 is set closer to the cleaning head 130, so that the center of gravity of the cleaning base 10 is moved forward, allowing the weight of the liquid supply tank 120 to act more on the cleaning head 130, thereby increasing the pressure on the ground of the cleaning head 130 set in front of the cleaning base 10.

[0074] The distance between the liquid supply tank 120 and the front side of the base body 110 is less than the distance between the liquid supply tank 120 and the rear side of the base body 110. That is, the liquid supply tank 120 is set close to the cleaning head 130, and the center of gravity of the cleaning base 10 is shifted forward, so that the weight of the liquid supply tank 120 can be applied more to the cleaning head 130, thereby increasing the pressure on the ground of the cleaning head 130 set in front of the cleaning base 10.

[0075] Among them, such as Figures 4-6 As shown, the liquid supply tank 120 is located on the side of the assist wheel 140 near the cleaning head 130, that is, it is set close to the cleaning head 130, so that the center of gravity of the liquid supply tank 120 is located on the side of the base body 110 near the cleaning head 130, so as to realize the forward shift of the center of gravity of the cleaning base 10.

[0076] In detail, along the forward direction of the handheld cleaning device, the liquid supply tank 120 can be located in front of the pivot of the assist wheel 140, so that the center of gravity of the liquid supply tank 120 is located on the base body 110 near the cleaning head 130. The center of gravity of the cleaning base 10 is moved forward, so that the weight of the liquid supply tank 120 can be applied more to the cleaning head 130, thereby increasing the pressure on the ground of the cleaning head 130 located in front of the cleaning base 10.

[0077] Furthermore, along the forward direction of the handheld cleaning device, the liquid supply tank 120 is located in front of the assist wheel 140, that is, the liquid supply tank 120 is positioned in front of the assist wheel 140, so that the center of gravity of the liquid supply tank 120 is located on the base body 110 closer to the cleaning head 130, thereby shifting the center of gravity of the cleaning base 10 forward. The weight of the liquid supply tank 120 itself can be applied more to the cleaning head 130, thereby further increasing the pressure on the ground exerted by the cleaning head 130 located in front of the cleaning base 10.

[0078] In this design, the orthographic projections of the liquid supply tank 120 and the cleaning head 130 onto the surface to be cleaned in a direction perpendicular to the horizontal plane (height direction Z) have at least a partial overlap, meaning at least a portion of the liquid supply tank 120 is directly above the cleaning head 130. By positioning at least a portion of the liquid supply tank 120 directly above the cleaning head 130, at least a portion of the weight of the liquid supply tank 120 can directly act on the cleaning head 130, increasing the pressure exerted on the ground by the cleaning head 130. This relatively increases the friction between the cleaning head 130 and the surface to be cleaned, thereby improving the cleaning effect. In some preferred embodiments, the orthographic projection of the liquid supply tank 120 onto a preset horizontal plane completely covers the orthographic projection of the cleaning head 130 along the height direction Z onto the preset horizontal plane. This allows more of the weight of the liquid supply tank 120 to directly act on the cleaning head 130, further increasing the pressure exerted on the ground by the cleaning head 130. This further relatively increases the friction between the cleaning head 130 and the surface to be cleaned, thereby further improving the cleaning effect. It should be noted that the preset horizontal plane may be, for example, a horizontal surface to be cleaned, a horizontal bearing surface of the base station 20, or a virtual horizontal plane in space.

[0079] In the left-right direction (second direction Y) of the cleaning base 10, the liquid supply tank 120 and the booster wheel 140 have an overlapping part, which can effectively utilize the space in the left-right direction of the cleaning base 10, so that the liquid supply tank 120 has a larger size in the left-right direction, thereby increasing the volume of the liquid supply tank 120.

[0080] The liquid supply tank 120 has a volume of 800ml to 1200ml, such as 800ml, 850ml, 900ml, 950ml, 1000ml, 1050ml, 1100ml, 1150ml, 1200ml, etc., which will not be listed here. Since the liquid supply tank 120 is located on the side of the assist wheel 140 near the cleaning head 130, the size of the liquid supply tank 120 can be designed to be relatively large, so that the liquid supply tank 120 can meet the requirement of a volume of 800ml or more, thereby increasing the usable time of the cleaning solution in the handheld floor scrubber, and thus increasing the duration of a single continuous cleaning operation, thereby improving the user experience.

[0081] In some embodiments, when the cleaning base 10 docks with the base station 20, it can travel along the length direction (first direction X) of the base station 20 or move onto the base station 20 in a direction perpendicular to the horizontal direction (height direction Z) to perform at least one function such as docking, charging, self-cleaning, sewage discharge, and water replenishment on the base station 20. In other words, when the handheld cleaning device docks with the base station 20, it can simultaneously achieve push-in and placement docking methods, increasing the functionality of the cleaning system and improving the user experience. The horizontal direction is parallel to the surface to be cleaned.

[0082] like Figure 2 and Figure 3 As shown, the base station 20 includes a ramp 230, and a handheld cleaning device can travel along the first direction X through the ramp 230 to the base station 20; in the length direction of the base station 20, the base station 20 has a first pair of interfaces 221, and in the height direction Z of the base station 20, the base station 20 has a second pair of interfaces 222; the cleaning base 10 can dock with the base station 20 through the first pair of interfaces 221 or the second pair of interfaces 222.

[0083] It is understood that this disclosure allows the handheld floor scrubber to connect to the base station 20 along the vertical direction Z, such as... Figures 2-6 As shown, when the liquid supply tank 120 is detachably connected to the base body 110, the liquid supply tank 120 can be directly separated or connected from the top of the base body 110 along the height direction Z, improving the user experience. Specifically, when the liquid supply tank 120 is detachably connected to the base body 110, a quick-connect plug structure can be provided between the liquid supply tank 120 and the base body 110, allowing the flow of cleaning fluid through the plug structure after the liquid supply tank 120 is connected to the base body 110; when the liquid supply tank 120 is separated from the base body 110, the plug structure can block the liquid outlet on the liquid supply tank 120 to achieve automatic liquid supply.

[0084] Among them, such as Figures 4-6 As shown, the cleaning head 130 and the liquid supply tank 120 are positioned on the same side of the base body 110 along the first direction X. The weight of the liquid supply tank 120 is thus more effectively distributed on the cleaning head 130, increasing the pressure exerted on the ground and increasing the friction between the cleaning head 130 and the surface to be cleaned, thereby improving the cleaning effect. Simultaneously, by positioning the cleaning head 130 and the liquid supply tank 120 on the same side of the base body 110 along the first direction X, the distance between the liquid supply tank 120 and the main body of the equipment is increased, facilitating the direct removal or assembly of the liquid supply tank 120 from the top of the base body 110.

[0085] It is understandable that when the supply tank 120 needs to be directly removed or assembled from above the base body 110, since the equipment body and the cleaning base 10 are movably connected, interference can be avoided when directly removing or assembling the supply tank 120 from above the base body 110 by rotating the equipment body at a certain angle. Of course, when disassembling the supply tank 120, the equipment body can be in an upright vertical position, and the supply tank 120 can be disassembled along an oblique upward direction. In other words, the disassembly and assembly of the supply tank 120 is not entirely along a direction parallel to the height direction Z, but can be completed from above the cleaning base 10.

[0086] Among them, such as Figure 7 and Figure 8 As shown, the base station 20 includes a main body 210, and a ramp 230 is located on one side of the main body 210 along a first direction X. The ramp 230 includes a first end and a second end in opposite directions X. The first end is connected to the main body 210, and the second end is positioned on the bearing surface (the plane on which the base station 20 is placed) of the base station 20. By providing the ramp 230, the cleaning base 10 can be directly connected to the base station 20 from the bearing surface around the base station 20 by the user's push, without the user having to lift the cleaning base 10. This facilitates the connection between the cleaning base 10 and the base station 20 and improves the user experience.

[0087] In some embodiments, the cleaning base 10 has a push-in guide structure configured to guide the cleaning base 10 when the handheld cleaning device moves horizontally onto the base station 20, i.e., to guide the cleaning base 10 to dock with the base station 20 through the first pair of interfaces 221. By providing the push-in guide structure, a guiding effect can be formed when the user pushes the cleaning base 10 to dock with the base station 20, enabling the cleaning base 10 and the base station 20 to dock accurately and quickly, thereby improving the user experience.

[0088] Among them, such as Figure 7 and Figure 8 As shown, the push-in guide structure includes at least one first guide wheel 251. By setting the first guide wheel 251, when the user pushes the cleaning base 10 to dock with the base station 20, the rotation of the first guide wheel 251 can form a guiding effect. At the same time, the first guide wheel 251 can reduce the resistance when the cleaning base 10 docks with the base station 20, thereby reducing the pushing force required by the user when pushing the cleaning base 10 to dock with the base station 20, thus improving the user experience.

[0089] Among them, such as Figure 7 and Figure 8 As shown, the ramp 230 is equipped with a first guide wheel 251. When the user pushes the cleaning base 10 on the ramp 230, since the ramp 230 is in an inclined state, the cleaning base 10 is in a climbing state. The first guide wheel 251 can reduce the resistance of the cleaning base 10 on the ramp 230, thereby reducing the pushing force required by the user and improving the user experience.

[0090] Among them, such as Figure 7 and Figure 8As shown, two first guide wheels 251 can be provided on the ramp 230. The two first guide wheels 251 can be spaced apart along the width direction (second direction Y) of the base station 20 and positioned close to the first pair of interfaces 221 along the length direction of the base station 20, so as to form a better guiding effect at the transition position where the ramp 230 connects to the first pair of interfaces 221, and to avoid the bottom of the cleaning base 10 rubbing against the top of the ramp 230. Of course, more first guide wheels 251 can also be provided on the ramp 230, and multiple first guide wheels 251 can also be provided at other positions on the ramp 230. This disclosure does not limit this.

[0091] The first guide wheel 251 can be rotatably mounted via a first rotating shaft. A first mounting groove can be formed on the ramp plate 230, and the first rotating shaft is located in the first mounting groove. That is, the portion of the first guide wheel 251 above the first rotating shaft can protrude from the surface of the ramp plate 230, thus providing support and guidance for the cleaning base 10 while preventing the first guide wheel 251 from being too high. The first guide wheel 251 and the first rotating shaft can be an integral structure or a separate structure.

[0092] The first rotating shaft is perpendicular to the length direction of the base station 20, meaning the rotation direction of the first guide wheel 251 is along the length direction of the base station 20 towards the front or rear of the base station 20. This provides better guidance when the cleaning base 10 docks with or separates from the base station 20 along the first direction X. Of course, the first guide wheel 251 can also be a caster wheel; this disclosure does not limit its use.

[0093] Among them, such as Figure 7 and Figure 8 As shown, the ramp 230 is provided with an anti-slip structure 270, which is located in the area traversed by the assist wheel 140 of the cleaning base 10 to prevent the assist wheel 140 from slipping when the cleaning base 10 climbs on the ramp 230. The anti-slip structure 270 may be a raised stripe structure formed on the surface of the ramp 230, and the extension direction of the stripe structure may be a second direction Y, that is, perpendicular to the travel direction of the assist wheel 140 on the ramp 230.

[0094] In some embodiments, the cleaning base 10 has an insertion guide structure configured to guide the cleaning base 10 to dock with the base station via the second pair of interfaces 222. By providing the insertion guide structure, a guiding effect can be achieved when the user lifts the cleaning base 10 to dock with the base station 20, enabling the cleaning base 10 and the base station 20 to dock accurately and quickly, thereby improving the user experience.

[0095] Among them, such as Figure 7 and Figure 8As shown, the base station 20 also includes a first side portion 241, a second side portion 242, and a third side portion 243. The first side portion 241 and the ramp plate 230 are located on both sides of the main body 210 along the first direction X. The second side portion 242 and the third side portion 243 are located on both sides of the base station 20 along a direction perpendicular to the direction in which the cleaning equipment travels to the base station 20 (the second direction Y). The first side portion 241, the second side portion 242, and the third side portion 243 enclose a groove structure. The opening of the groove structure in the first direction X forms a first pair of interfaces 221, and the opening of the groove structure in the height direction Z forms a second pair of interfaces 222. By setting the second side portion 242 and the third side portion 243, when the cleaning base 10 is lifted and docked with the base station 20 through the second pair of interfaces 222, a guide is formed for placing it into the groove structure, which is beneficial for docking the cleaning base 10 with the base station 20 and can improve the user experience.

[0096] Among them, such as Figure 7 and Figure 8 As shown, a second guide wheel 252 is provided on the sidewall of the second side portion 242 and / or the third side portion 243 facing the second direction Y. By providing the second guide wheel 252 on the sidewall of the second side portion 242 and / or the third side portion 243 facing the second direction Y, i.e., the second guide wheel 252 is located within the groove structure, when the user pushes the cleaning base 10 to connect with the base station 20, the rotation of the second guide wheel 252 can guide the cleaning base 10 within the groove structure. Simultaneously, the second guide wheel 252 reduces the resistance when the cleaning base 10 connects with the base station 20, thereby reducing the pushing force required by the user and improving the user experience. Furthermore, the rotation of the second guide wheel 252 prevents direct contact between the cleaning base 10 and the second side portion 242 and the third side portion 243, avoiding hard contact that could cause scratches on the outer casing and thus preventing damage to the appearance of the handheld cleaning device.

[0097] Among them, such as Figure 7 and Figure 8 As shown, a second guide wheel 252 is provided on each of the second side portion 242 and the third side portion 243, and is positioned close to the ramp plate 230 in the first direction X. This allows the guide wheel to contact the side wall of the cleaning base 10 promptly when it enters the groove structure through the first pair of interfaces 221, thus guiding the cleaning base 10. Of course, more second guide wheels 252 can be provided on the second side portion 242 and the third side portion 243, and multiple second guide wheels 252 can also be positioned at other locations on the second side portion 242 and the third side portion 243. This disclosure does not impose any limitations on this.

[0098] The second guide wheel 252 can be rotatably mounted via a second rotating shaft. Second mounting grooves can be formed on the second side portion 242 and the third side portion 243, respectively. The second rotating shaft is located within the second mounting groove, meaning that the portion of the second guide wheel 252 located on the radial side of the second rotating shaft can protrude from the sidewalls of the second side portion 242 and the third side portion 243, respectively. The second guide wheel 252 and the second rotating shaft can be an integral structure or a separate structure.

[0099] In this design, the surface of the second guide wheel 252 is inclined along a direction perpendicular to the horizontal plane. The diameter of the second guide wheel 252 at this inclined surface decreases towards the side furthest from the base station 20 in the direction perpendicular to the horizontal plane upwards. Specifically, the surface of the second guide wheel 252 facing the second interface 222 in the height direction Z is inclined, and the diameter of the second guide wheel 252 increases from the second interface 222 towards the bottom of the groove structure. When the cleaning base 10 is inserted into the groove structure through the second interface 222 to connect with the base station 20, the inclined surface of the second guide wheel 252 provides guidance, improving the smoothness of the connection between the cleaning base 10 and the base station 20, preventing jamming, and thus enhancing the user experience.

[0100] In some embodiments, the base station 20 is provided with a docking structure, which includes a charging docking structure and / or a communication docking structure. When the cleaning base 10 moves to the base station 20, it can be charged through the base station 20 and / or communicate with the base station 20.

[0101] Among them, such as Figure 4 and Figure 5 As shown, the cleaning base 10 has a first charging terminal 151 and a second charging terminal 152 on both sides in a direction perpendicular to the direction in which the cleaning equipment travels to the base station 20 (width direction). Figure 7 and Figure 8 As shown, the charging docking structure includes a third charging terminal 2611 disposed on the second side 242 and a fourth charging terminal 2612 disposed on the third side 243. After the cleaning base 10 is docked with the base station 20, the first charging terminal 151 is connected to the third charging terminal 2611, and the second charging terminal 152 is connected to the fourth charging terminal 2612. The first charging terminal 151 and the third charging terminal 2611 may have the same polarity, the second charging terminal 152 and the fourth charging terminal 2612 may have the same polarity, and the first charging terminal 151 and the second charging terminal 152 may have opposite polarities.

[0102] After the cleaning base 10 is connected to the base station 20, the handheld floor scrubber can be charged through the charging terminals located on both sides of the cleaning base 10 and both sides of the base station 20. This allows the cleaning base 10 and the base station 20 to be charged after being connected through either the first pair of interfaces 221 or the second pair of interfaces 222.

[0103] In some embodiments, the angle between the ramp 230 and the horizontal plane is no greater than 20°, so that the upward angle of the cleaning base 10 can be controlled below 20°, which can improve the user's experience of pushing the cleaning base 10 upward.

[0104] The angle between the ramp slab 230 and the horizontal plane can be 10° to 20°, such as 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, etc., which will not be listed here.

[0105] like Figure 9 As shown, the base station 20 includes a drying module 281. The main body 210 has a receiving space, and an air outlet 212 is provided on the first side 241. The drying module 281 is disposed in the receiving space of the main body 210 and is configured to output hot air through the air outlet 212. The drying module 281 is disposed in the main body 210, utilizing the space of the main body 210 and avoiding the drying module 281 occupying the space of the base station 20 in the first direction X. While the length of the base station 20 remains unchanged or substantially unchanged, the length of the ramp 230 is relatively increased. After the length of the ramp 230 is increased, the slope of the ramp 230 can be relatively reduced, ultimately allowing the upper pile angle of the cleaning base 10 to be controlled below 20°, saving the thrust required by the user and improving the user experience.

[0106] Among them, the ramp 230 is a sloping plane for supporting the handheld cleaning equipment. That is, the ramp surface of the ramp 230 is an inclined plane. When the cleaning base 10 travels on the ramp 230, there is no bump caused by the change of slope, and the stability is good, which can improve the user's experience of pushing the cleaning base 10 onto the pile.

[0107] It is understood that the ramp slab 230 may also include multiple slopes along the first direction X, with adjacent slopes directly connected or connected through a transition surface; the angle between the transition surface and the horizontal plane is smaller than the angle between the two adjacent slopes and the horizontal plane. The angles between the multiple slopes and the horizontal plane may be the same or different, and the angles with the horizontal plane can be 10° to 20°.

[0108] Among them, such as Figure 9As shown, a cleaning groove 211 is formed on the main body 210, which is used to place the cleaning head 130 of the cleaning base 10. The air outlet 212 can be located on the first side 241, that is, along the height direction Z, the air outlet 212 is located above the cleaning groove 211, so that hot air at a preset temperature is output through the air outlet 212 to dry the cleaning roller. The preset temperature can be 40℃~90℃, such as 40℃, 45℃, 50℃, 55℃, 60℃, 65℃, 70℃, 75℃, 80℃, 85℃, 90℃, etc., which will not be listed here. By using high-temperature drying gas, the cleaning roller can be dried quickly, so as to avoid problems such as odor and bacterial growth caused by moisture, thus improving the user experience.

[0109] Among them, such as Figure 9 As shown, multiple air outlets 212 are distributed in the width direction of the base station 20. The width of the distribution area can be comparable to the length of the cleaning roller, so as to dry all positions in the axial direction of the cleaning roller at the same time and improve the drying effect.

[0110] Among them, such as Figure 9 As shown, multiple air outlets 212 can be set in the height direction Z of the base station 20, for example, two air outlets 212 can be set to simultaneously dry multiple positions on the circumference of the cleaning roller, thereby improving the drying effect. When multiple air outlets 212 are set, the two air outlets 212 corresponding to two adjacent air outlets 212 in the height direction Z can be staggered in the width direction, so that all positions on the circumference of the cleaning roller can be directly dried by hot air, thereby improving the drying effect.

[0111] In this system, after the cleaning base 10 is connected to the base station 20, the height of the first side portion 241 in the height direction Z can be greater than the height of the cleaning head 130 in the cleaning base 10. By making the height of the first side portion 241 greater than the height of the cleaning head 130 in the cleaning base 10, on the one hand, when the cleaning head 130 performs self-cleaning on the base station 20, the cleaning liquid sprayed by the cleaning head 130 will be thrown out during the rotation process. The higher first side portion 241 can form a barrier to the thrown cleaning liquid, preventing the cleaning liquid from being thrown out of the base station 20; on the other hand, when the self-cleaned cleaning head 130 is dried by the drying module 281, the higher first side portion 241 can extend the flow path of the drying gas around the cleaning head 130, thereby increasing the air temperature around the cleaning head 130 and thus improving the drying efficiency of the cleaning head 130.

[0112] Among them, such as Figures 9-12As shown, the base station 20 also includes a base plate 244 and a support plate 245. The first end of the ramp plate 230 is connected to the support plate 245, and a cleaning groove 211 is formed on the support plate 245. The base plate 244, the first side portion 241, the second side portion 242, the third side portion 243, the support plate 245, and the ramp plate 230 enclose a receiving space under the support plate 245 and a receiving space under the ramp plate 230. That is, target devices can be assembled under both the support plate 245 and the ramp plate 230 to save the size of the main body portion 210 in the first direction X.

[0113] Among them, such as Figure 9 , Figure 11 and Figure 12 As shown, the drying module 281 includes a fan 2811, a fan housing 2812, a heater 2813, and an air duct 2814. The fan 2811 is assembled inside the fan housing 2812, which is connected to a support plate 245. The air inlet of the heater 2813 is connected to the air outlet 212 of the fan housing 2812, and the air outlet 212 of the heater 2813 is connected to the air inlet of the air duct 2814. The air outlet 212 of the air duct 2814 is the same as the air outlet 212 on the first side 241. There is a gap between the fan housing 2812 and the support plate 245, which serves as the air inlet of the fan housing 2812. The fan housing 2812 and the support plate 245 can be connected by screws, so that there is a gap around the fan housing 2812 and the support plate 245 in the rotation direction of the fan 2811, allowing air to enter through a circumferential ring.

[0114] Among them, such as Figures 9-12 As shown, an air inlet structure 282 is provided on the base plate 244. The gap between the fan housing 2812 and the support plate 245 is connected to the air inlet structure 282 so that air from the outside of the base station 20 can be drawn in through the air inlet structure 282. After being heated by the heater 2813, the air inlet structure 282 dries the cleaning roller through the air outlet 212.

[0115] The air intake structure 282 can be a grid structure formed on the base plate 244. The air intake structure 282 can sink down along the height direction Z towards the support plate 245 to increase the distance between the air intake structure 282 and the bearing surface of the base station 20, which is conducive to the air at the bottom of the base station 20 entering the fan 2811 through the air intake structure 282.

[0116] The air inlet structure 282 is equipped with a filter element 283, which is located in the receiving space. The filter element 283 filters the air drawn in through the air inlet structure 282, preventing foreign objects, dust, and sewage from entering the fan 2811 through the air inlet structure 282, thus improving the service life and reliability of the fan 2811. The filter element 283 can be, for example, a sponge, and can be secured to the air inlet structure 282 with hooks, improving the cost-effectiveness of later maintenance. Of course, the filter element 283 can also be a filter screen, paper-based filter element, etc., and can be fixed in the receiving space by adhesive, threaded connection, or other methods; this disclosure does not limit this.

[0117] Among them, such as Figures 9-12 As shown, the air intake structure 282 and the filter element 283 are located in the accommodating space below the ramp plate 230, saving the accommodating space below the support plate 245. This allows for a further reduction in the length of the base station body, while relatively increasing the length of the ramp plate 230, thus further reducing the slope of the ramp plate 230. It is understood that other devices of suitable height can be installed in the accommodating space below the ramp plate 230 to reduce the accommodating space occupied by the devices below the support plate 245, and this disclosure does not impose any limitations on this.

[0118] Among them, such as Figures 11-13 As shown, the base station 20 also includes a circuit board 291, which is disposed in the accommodating space. The air inlet of the fan 2811 and the orthographic projection of the circuit board 291 along the width direction on the preset reference plane have an overlapping portion, that is, the gap between the fan housing 2812 and the support plate 245 can draw in air around the circuit board 291, thereby increasing the air flow speed around the circuit board 291, reducing the temperature of the air around the circuit board 291, and achieving cooling of the circuit board 291, so that the circuit board 291 is within the normal operating temperature range.

[0119] The distance between the air intake structure 282 and the circuit board 291 along the first direction X is no more than 5cm, such as 5cm, 4cm, 3cm, 2cm, 1cm, etc., which can better improve the air flow speed around the circuit board 291, so as to reduce the temperature of the air around the circuit board 291 and achieve cooling of the circuit board 291.

[0120] Among them, such as Figure 13 As shown, a clearance notch 2910 is formed on the circuit board 291, which is located between the circuit board 291 and the heater 2813 along the width direction of the base station 20. The circuit board 291 avoids the heater 2813 through the clearance notch 2910, preventing the heat generated by the heater 2813 heating the gas sucked in by the fan 2811 from affecting the normal operation of the circuit board 291 and improving the reliability of the circuit board 291.

[0121] Among them, such as Figure 13 As shown, the heater 2813, circuit board 291, and fan 2811 are located between the drying air duct 2814 and the ramp 230 along the first direction X. That is, the heater 2813 and fan 2811 are distributed with the circuit board 291 in the width direction, which saves the space occupied by the base station body in the first direction X, thereby further shortening the length of the base station body, while relatively increasing the length of the ramp 230, and further reducing the slope of the ramp 230.

[0122] Among them, such as Figure 13 As shown, the base station 20 also includes a control component 292 and a charging component 293. The control component 292 and the charging component 293 are located between the drying air duct 2814 and the ramp 230 along the first direction X. That is, the control component 292 and the charging component 293 are distributed with the circuit board 291 in the width direction, saving the space occupied by the base station body in the first direction X, thereby further shortening the length of the base station body, while relatively increasing the length of the ramp 230, and further reducing the slope of the ramp 230. At the same time, the air inlet of the fan 2811 and the orthographic projection of the charging component 293 along the width direction on the preset reference plane have an overlapping part. That is, the gap between the fan housing 2812 and the support plate 245 can draw in the air around the charging component 293, thereby increasing the air flow speed around the charging component 293, reducing the temperature of the air around the charging component 293, and cooling the charging component 293 so that the charging component 293 is within the normal operating temperature range.

[0123] The base plate 244 and the support plate 245 can be used together to form an air duct 2814, that is, the base plate 244 and the support plate 245 are fastened together to form an air duct 2814; the air duct 2814 can also be formed directly on the support plate 245 or the base plate 244, or the air duct 2814 can be formed as an independent structural component set between the base plate 244 and the support plate 245. This disclosure does not limit this.

[0124] The base plate 244 can be provided with an assembly structure for assembling the heater 2813, circuit board 291, control component 292, and charging component 293, forming a positioning assembly and improving the assembly efficiency, assembly accuracy, and post-assembly stability of each component in the base station 20. The assembly structure corresponding to each component only needs to match the shape and size of each component; this disclosure does not impose any limitations in this regard.

[0125] In some embodiments, the docking structure includes a transmission component, such as... Figures 14-16As shown, the docking structure 260 includes a transmission head 261 and a mounting base 262. The transmission head 261 can be mounted on the mounting base 262, and the transmission head 261 is used to transmit electrical energy and / or electrical signals to the handheld cleaning device. It can be understood that the transmission head 261 can be used to transmit electrical energy to the handheld cleaning device for charging, or it can be used to transmit electrical signals to the handheld cleaning device for information interaction, or it can simultaneously transmit both electrical energy and electrical signals to the handheld cleaning device, thus simultaneously fulfilling the functions of charging and interacting with the handheld cleaning device.

[0126] The mounting base 262 can be installed on the side of the main body 210 near the recessed structure, thereby saving height space and reducing the thickness of the base station 20. Furthermore, since the transmission head 261 is mounted on the mounting base 262, when the mounting base 262 is installed on the side of the main body 210 near the recessed structure, the main body 210 can provide protection for both the transmission head 261 and the mounting base 262, preventing damage from external impacts.

[0127] Furthermore, the mounting base 262 can be mounted on the side of the base station 210 near the recessed structure. Alternatively, the mounting base 262 can be mounted on the side of the main body 210 near the recessed structure. Alternatively, the mounting base 262 can be mounted on both the side of the base station 210 near the recessed structure and the side of the main body 210 near the recessed structure. This arrangement can further save height space of the base station 20 and further reduce the thickness of the base station 20.

[0128] The mounting base 262 may have a first initial position and a first avoidance position, with the first avoidance position being farther away from the groove structure relative to the first initial position. During the placement of the handheld cleaning device on the base station 20, the mounting base 262 can switch from the first initial position to the first avoidance position, allowing it to move away from the groove structure. This avoids hard contact between the mounting base 262 and the handheld cleaning device, reducing the probability of damage to both and improving the lifespan and stability of the base station 20.

[0129] Meanwhile, when the mounting base 262 switches from the first initial position to the first avoidance position, the mounting base 262 can drive the transmission head 261 to move away from the groove structure, which can also prevent the transmission head 261 from making hard contact with the handheld cleaning device. This can slow down the wear rate of the transmission head 261, improve the docking effect between the base station 20 and the handheld cleaning device, and ensure the stability of the transmission head 261 in transmitting power and / or transmitting electrical signals. This can further improve the service life and operational stability of the base station 20.

[0130] In some embodiments, the mounting base 262 may also have a first working position. When the mounting base 262 is in the first working position, the transmission head 261 may be electrically connected to the handheld cleaning device to deliver electrical power and / or transmit electrical signals to the handheld cleaning device.

[0131] The first working position can be close to the groove structure relative to the first clearance position; that is, the first working position can be located between the first clearance position and the first initial position, or the first working position can be the first initial position. After the handheld cleaning device is placed in the groove structure, the mounting base 262 can switch from the first clearance position to the first working position. It is understood that when the handheld cleaning device is placed in the groove structure, the mounting base 262 can move towards the groove structure to switch to the first working position, thereby enabling the transmission head 261 to contact the electrical connection structure on the handheld cleaning device, allowing the transmission head 261 to stably deliver electrical energy and / or electrical signals to the handheld cleaning device.

[0132] like Figure 17 As shown, the docking structure 260 may further include a first moving member 2631. The first moving member 2631 may be configured to switch the mounting base 262 from a first clearance position to a first working position. Furthermore, when the first working position is between the first initial position and the first clearance position, the first moving member 2631 may also be configured to switch the mounting base 262 from the first working position to the first initial position, so that after the handheld cleaning device is disengaged from the groove structure, the mounting base 262 can be reset, thereby ensuring that the next docking can proceed normally.

[0133] The first moving component 2631 can be a first elastic component. The first elastic component can be a spring, but is not limited to this; it can also be made of soft rubber, etc. The first elastic component can be disposed between the mounting base 262 and the side portion. When the mounting base 262 is in the first clearance position, the first elastic component can have a restoring force, thereby allowing the first elastic component to drive the mounting base 262 to switch to the first working position, or the first elastic component to drive the mounting base 262 to switch to the first initial position. This configuration ensures that the first moving component 2631 can drive the mounting base 262 to move while reducing the manufacturing cost of the first moving component 2631.

[0134] like Figure 17 and Figure 18As shown, the docking structure 260 may further include a first guide structure 2641. The first guide structure 2641 may be disposed on the side, or it may be disposed on the mounting base 262, or both the mounting base 262 and the side may have the first guide structure 2641. Furthermore, the first guide structure 2641 can be used to provide guidance for the mounting base 262 when it changes position, ensuring that the mounting base 262 can move accurately along a predetermined direction.

[0135] The first guide structure 2641 can be disposed on the side near the groove structure to avoid occupying other space on the side. It also prevents positional interference between the first guide structure 2641 and the handheld cleaning device during and after placement in the groove structure. However, it is not limited to this; the first guide structure 2641 can also be disposed in other positions on the side, depending on the actual situation, all of which are within the scope of this disclosure.

[0136] The first guide structure 2641 can be a first guide post, and the first elastic member can be sleeved on the outer circumferential surface of the first guide post to limit the first elastic member by the first guide post, so as to prevent the first elastic member from shifting position or falling off when the mounting base 262 switches positions, thereby improving the stability of the mounting base 262 when switching positions and improving the service life of the base station 20.

[0137] The device can have two first elastic elements and two first guide posts. The two first guide posts are diagonally positioned on the side near the groove structure, and the two first elastic elements are respectively fitted onto the outer circumferential surfaces of the two first guide posts. This arrangement improves the accuracy and stability of the mounting base 262's movement when switching positions. Furthermore, having only two first guide posts and two first elastic elements diagonally avoids the problem of the mounting base 262 jamming due to excessive number of first guide posts and first elastic elements during movement, ensuring smooth position switching of the mounting base 262.

[0138] Alternatively, the first guide structure 2641 can also be disposed on the side of the mounting base 262 opposite to the groove structure, to avoid the first guide structure 2641 occupying the circumferential space of the mounting base 262, facilitating the placement of other structural components around the mounting base 262. Furthermore, it can also prevent positional interference between the first guide structure 2641 and the handheld cleaning device during and after placement in the groove structure when the first guide structure 2641 is disposed in other positions on the mounting base 262. However, this is not a limitation; the first guide structure 2641 can also be disposed on the circumferential surface of the mounting base 262, and can be selected and disposed according to actual conditions, all of which are within the protection scope of this disclosure.

[0139] When the first guide structure 2641 is disposed on the side of the mounting base 262 opposite to the groove structure, the two first guide posts can be diagonally disposed on the same side of the mounting base 262 opposite to the groove structure, and the two first elastic elements can be respectively sleeved on the outer circumferential surfaces of the two first guide posts. This arrangement can improve the accuracy and stability of the movement of the mounting base 262 when switching positions. At the same time, arranging only two first guide posts and two first elastic elements diagonally can avoid the problem of jamming of the mounting base 262 due to excessive limitation during movement caused by an excessive number of first guide posts and first elastic elements, thus ensuring the smoothness of the mounting base 262 switching positions.

[0140] The first guide post can be a cross-shaped guide post, which can reduce manufacturing costs while ensuring high structural strength. However, it is not limited to this; the first guide post can also be cylindrical, prismatic, etc., and can be selected and set according to the actual situation. Of course, the first guide structure 2641 can also be something other than a first guide post. For example, the first guide structure 2641 can be a guide groove or a guide block, which is also within the protection scope of this disclosure.

[0141] In some embodiments, the first moving member 2631 can be an active driving member. For example, the first moving member 2631 may include a driving part and a connecting part. The connecting part can be connected to the mounting base 262, and the driving part can drive the connecting part to move in a direction close to or away from the groove structure, so that the connecting part can drive the mounting base 262 to switch from a first clearance position to a first working position, and can drive the mounting base 262 to switch from the first working position to a first initial position.

[0142] When the first moving member 2631 is an active driving member, the first moving member 2631 can also be configured to switch the mounting base 262 from the first initial position to the first avoidance position. That is, when the handheld cleaning device is placed in the groove structure, the first moving member 2631 can actively drive the mounting base 262 from the first initial position to the first avoidance position to avoid the handheld cleaning device.

[0143] In other embodiments, the first working position can be a first avoidance position, that is, when the mounting base 262 reaches the first avoidance position, the transmission head 261 can be electrically connected to the handheld cleaning device, which is also within the protection scope of this disclosure.

[0144] In some embodiments, such as Figures 14 to 17 As shown, both the first docking structure 2601 and the second docking structure 2602 may include a second guide wheel 252. The second guide wheel 252 is rotatably mounted on the mounting base 262, and provides guidance for the handheld cleaning device during the placement of the handheld cleaning device into the groove structure.

[0145] The maximum distance between the second guide wheel 252 and the mounting base 262 in the second direction Y can be greater than the maximum distance between the transmission head 261 and the mounting base 262 in the second direction Y, meaning the second guide wheel 252 protrudes from the transmission head 261. With this configuration, when the handheld cleaning device is placed in the recessed structure, the second guide wheel 252 can support the handheld cleaning device, preventing it from contacting the transmission head 261 and thus avoiding wear on the transmission head 261.

[0146] like Figure 16 As shown, the second guide wheel 252 may include a first guide surface 2521 and a second guide surface 2522. The second guide surface 2522 may be disposed on the side of the first guide surface 2521 away from the main body 210, that is, when the base station 20 is placed on the ground, the second guide surface 2522 may be disposed above the first guide surface 2521. The second guide surface 2522 may be inclined in a direction close to the axis of the second guide wheel 252. It is understood that the second guide surface 2522 may be a conical surface or a partially conical surface. With this configuration, the second guide surface 2522 can be used to guide the handheld cleaning device when it is vertically inserted into the groove structure or when it is vertically removed from the groove structure, thereby improving the smoothness of inserting and removing the handheld cleaning device.

[0147] The first guide surface 2521 and / or the second guide surface 2522 can be made of soft rubber. This design prevents the first guide surface 2521 and / or the second guide surface 2522 from abrading the handheld cleaning device. However, this is not a limitation; the first guide surface 2521 and / or the second guide surface 2522 can also be made of other softer materials, such as foam, which can be selected and set according to the actual situation.

[0148] In some embodiments, the projections of the second guide wheel 252 along its axial extension direction and the projections of the transmission head 261 along the axial extension direction of the second guide wheel 252 may at least overlap. This arrangement reduces the horizontal distance between the second guide wheel 252 and the transmission head 261, saving space in the mounting base 262 and improving the integration of the docking structure 260. The axial extension direction of the second guide wheel 252 may intersect the horizontal direction; for example, the angle between the axial extension direction of the second guide wheel 252 and the horizontal direction may be 90°.

[0149] The projections of the second guide wheel 252 and the transmission head 261 in the horizontal direction can at least overlap. This arrangement reduces the vertical distance between the second guide wheel 252 and the transmission head 261, saving space in the mounting base 262 and improving the integration of the docking structure 260.

[0150] Specifically, the projections of the second guide wheel 252 along its axial extension direction and the transmission head 261 along the axial extension direction of the second guide wheel 252 can at least overlap, and the projections of the second guide wheel 252 and the transmission head 261 in the horizontal direction can also at least overlap. This arrangement further reduces the distance between the second guide wheel 252 and the transmission head 261, further saves space in the mounting base 262, and further improves the integration of the docking structure 260.

[0151] In some embodiments, such as Figures 19 to 21 As shown, the mounting base 262 may include a first plate portion 2621 and a second plate portion 2622. The first plate portion 2621 may have a first through hole, and the second plate portion 2622 and the first plate portion 2621 may be disposed opposite to each other, and the second plate portion 2622 may be located away from the recessed structure relative to the first plate portion 2621. The transmission head 261 may be mounted on the second plate portion 2622, and at least a portion of the transmission head 261 may protrude through the first through hole for electrical connection with a handheld cleaning device.

[0152] The transmission head 261 may have a second initial position and a second avoidance position, with the second avoidance position being farther away from the groove structure relative to the second initial position. During the placement of the handheld cleaning device into the groove structure, the transmission head 261 can switch from the second initial position to the second avoidance position. That is, during the placement of the handheld cleaning device into the groove structure, the transmission head 261 can move away from the groove structure, thereby avoiding hard contact between the transmission head 261 and the handheld cleaning device, reducing the degree of wear on the transmission head 261, and further improving the service life and operational stability of the base station 20.

[0153] In some embodiments, the transmission head 261 may also have a second operating position. When the transmission head 261 is in the second operating position, the transmission head 261 may be electrically connected to the handheld cleaning device to deliver electrical power and / or transmit electrical signals to the handheld cleaning device.

[0154] The second working position can be close to the groove structure relative to the second clearance position; that is, the second working position can be located between the second clearance position and the second initial position, or the second working position can be the second initial position. After the handheld cleaning device is placed in the groove structure, the transmission head 261 can switch from the second clearance position to the second working position. It is understood that when the handheld cleaning device is placed in the groove structure, the transmission head 261 can move towards the groove structure to switch to the second working position, thereby enabling the transmission head 261 to contact the electrical connection structure on the handheld cleaning device, allowing the transmission head 261 to stably deliver electrical energy and / or electrical signals to the handheld cleaning device.

[0155] like Figure 20 As shown, the docking structure 260 may further include a second moving member 2632. The second moving member 2632 may be configured to switch the transmission head 261 from a second clearance position to a second working position. Furthermore, when the second working position is between the second initial position and the second clearance position, the second moving member 2632 may also be configured to switch the transmission head 261 from the second working position to the second initial position, so that after the handheld cleaning device detaches from the groove structure, the transmission head 261 can be reset, thereby ensuring that the next docking can proceed normally.

[0156] The second moving member 2632 can be a second elastic member. The second elastic member can be a spring, but is not limited to this; it can also be made of soft rubber, etc. The second elastic member can be disposed between the transmission head 261 and the second plate portion 2622. When the transmission head 261 is in the second clearance position, the second elastic member can have a restoring force, thereby driving the transmission head 261 to switch to the second working position, or driving the transmission head 261 to switch to the second initial position. This configuration ensures that the second moving member 2632 can drive the transmission head 261 to move while reducing the manufacturing cost of the second moving member 2632.

[0157] like Figure 20 and Figure 21 As shown, the docking structure 260 may further include a second guide structure 2642. The second guide structure 2642 may be disposed on the second plate portion 2622, and the second guide structure 2642 may be used to provide guidance for the transmission head 261 when the transmission head 261 switches positions, so as to ensure that the transmission head 261 can move accurately along a predetermined direction.

[0158] The second guide structure 2642 can be a second guide post, and the second elastic member can be sleeved on the outer circumferential surface of the second guide post. The second guide post can be used to limit the second elastic member, so as to prevent the second elastic member from shifting position or falling off when the transmission head 261 switches positions. This can improve the stability of the transmission head 261 switching positions and increase the service life of the base station 20.

[0159] The second guide post can be a cross-shaped guide post, which can reduce manufacturing costs while ensuring high structural strength. However, it is not limited to this; the second guide post can also be cylindrical, prismatic, etc., and can be selected and set according to the actual situation. Of course, the second guide structure 2642 can also be something other than a second guide post. For example, the second guide structure 2642 can be a guide groove or a guide block, which is also within the protection scope of this disclosure.

[0160] In some embodiments, the second moving member 2632 can be an active driving member. For example, the second moving member 2632 may include a driving part and a connecting part. The connecting part can be connected to the transmission head 261, and the driving part can drive the connecting part to move in a direction close to or away from the groove structure, so that the connecting part can drive the transmission head 261 to switch from a second avoidance position to a second working position, and can drive the transmission head 261 to switch from the second working position to a second initial position.

[0161] When the second moving member 2632 is an active driving member, the second moving member 2632 can also be configured to switch the transmission head 261 from the second initial position to the second avoidance position. That is, when the handheld cleaning device is placed in the groove structure, the second moving member 2632 can actively drive the transmission head 261 from the second initial position to the second avoidance position to avoid the handheld cleaning device.

[0162] In other embodiments, the second working position can be a second avoidance position, that is, the transmission head 261 can be electrically connected to the handheld cleaning device when it reaches the second avoidance position, which is also within the protection scope of this disclosure.

[0163] In some embodiments, such as Figure 16 and Figure 20As shown, the first plate portion 2621 may have a third guide surface 2623. The third guide surface 2623 may be disposed on the side of the first plate portion 2621 near the groove structure and may surround at least part of the first through hole. The third guide surface 2623 may be inclined toward the axis of the first through hole, and the third guide surface 2623 is not on the movement path of the transmission head 261. With this configuration, the third guide surface 2623 can guide the handheld cleaning device during the placement of the handheld cleaning device into the groove structure, preventing the handheld cleaning device from colliding with the transmission head 261 and damaging the transmission head 261. At the same time, the third guide surface 2623 can guide the electrical connection of the handheld cleaning device to the transmission head 261, ensuring that the handheld cleaning device can be accurately electrically connected to the transmission head 261.

[0164] The third guide surface 2623 can be arranged around the first through hole, so that the third guide surface 2623 is a partially conical surface. With this arrangement, when the handheld cleaning device is placed in the groove structure from any direction, the third guide surface 2623 can guide the handheld cleaning device.

[0165] The first plate portion 2621 may also have a fourth guide surface 2624. The fourth guide surface 2624 may extend along the axial direction of the first through hole and connect the first plate portion 2621 and the third guide surface 2623 at the end away from the first plate portion 2621, so as to improve the guidance of the movement of the transmission head 261 and further improve the accuracy of the movement of the transmission head 261.

[0166] Furthermore, the outer peripheral surface of the transmission head 261 can contact the fourth guide surface 2624. This configuration can further improve the guiding capability of the fourth guide surface 2624 for the transmission head 261.

[0167] In some embodiments, there may be a gap between the first plate portion 2621 and the second plate portion 2622. This arrangement provides sufficient movement space for the transmission head 261. The first gap 2625 may be less than or equal to 6 mm to avoid the problem of excessive thickness of the mounting base 262 due to an excessively large first gap 2625, and at the same time, it can also reduce the movement stroke of the transmission head 261 during movement.

[0168] The transmission head 261 may include a body portion 2661 and a stop portion 2662. At least a portion of the body portion 2661 can extend through a first through hole for electrical connection with a handheld cleaning device. The stop portion 2662 can be connected to the body portion 2661, and at least a portion of the stop portion 2662 is located between a first plate portion 2621 and a second plate portion 2622 to limit the body portion 2661, preventing it from falling out of the first through hole during movement, thereby further improving the service life and operational stability of the base station 20.

[0169] In some embodiments, such as Figure 14 and Figure 15 As shown, the base station 20 may include: a first docking structure 2601 and a second docking structure 2602. The first docking structure 2601 may include a first mounting base 2651 and a first transmission head (a third charging terminal 2611). The second docking structure 2602 may be disposed at an interval from the first docking structure 2601, and the second docking structure 2602 may include a second mounting base 2652 and a second transmission head (a fourth charging terminal 2612).

[0170] The first and second transmission heads can have opposite polarities, meaning both can be used to transmit electrical energy, and can be the first positive and negative terminals, respectively. This configuration allows for a larger gap between the positive and negative terminals of the base station 20, preventing short circuits.

[0171] In addition, the first and second transmission heads can also be used to transmit electrical energy and electrical signals, respectively; that is, one of the first and second transmission heads can be an electrode, and the other can be a signal transmission end. By arranging the first docking structure 2601 and the second docking structure 2602 at intervals, the distance between the electrode and the signal transmission end can be increased, avoiding the problem of short circuits between the electrode and the signal transmission end.

[0172] The first mating structure 2601 can be disposed on the second side 242, and the second mating structure 2602 can be disposed on the third side 243. That is, the first mounting base 2651 can be mounted on the side of the second side 242 near the groove structure, and the second mounting base 2652 can be mounted on the side of the third side 243 near the groove structure. Because the second side 242 and the third side 243 are spaced apart, the distance between the first mating structure 2601 and the second mating structure 2602 can be further increased, further reducing the probability of short circuits.

[0173] Furthermore, when the second side portion 242 and the third side portion 243 are located on opposite sides of the main body portion 210, the first docking structure 2601 can be further moved away from the second docking structure 2602, further reducing the risk of a short circuit between the first transmission head and the second transmission head.

[0174] In some embodiments, the first transmission head can be a first negative electrode, and the second transmission head can be a first positive electrode. The distance between the first transmission head and the upper surface of the main body 210 can be smaller than the distance between the second transmission head and the upper surface of the main body 210.

[0175] The upper surface of the main body 210 can be used to support the handheld cleaning device after it is placed in the recessed structure. This means the first transmission head is positioned lower than the second transmission head. This arrangement prevents a short circuit between the first and second transmission heads due to water on the base station 20. Furthermore, since the first positive terminal is typically connected to an external power source and the first negative terminal is typically grounded, a short circuit will only occur when the water level on the base station 20 exceeds the second transmission head, further reducing the probability of a short circuit at the first negative terminal.

[0176] The distance between the first transmission head and the upper surface of the main body 210 can be greater than or equal to 20mm and less than or equal to 40mm. Examples include 20mm, 25mm, 30mm, 35mm, and 40mm. This arrangement avoids the first transmission head being too low and too close to the main body 210, thus reducing the probability of short circuits between the first transmission head and components on the main body 210. Simultaneously, it avoids the problem of the second transmission head needing to be set too high if the first transmission head is set too high, thereby reducing the height of the second side 242 and the third side 243, and consequently reducing the overall height of the base station 20.

[0177] The distance between the second transmission head and the upper surface of the main body 210 can be greater than or equal to 30mm and less than or equal to 70mm. For example, 30mm, 40mm, 50mm, 60mm, 70mm, etc. This setting ensures that the second transmission head has sufficient height to reduce the probability of short circuits. Simultaneously, it avoids the problem of needing to increase the height of the third side 243 due to the second transmission head being set too high, thus reducing the overall height of the base station 20.

[0178] In some embodiments, the second docking structure 2602 may further include a third transmission head 2613. The third transmission head 2613 can be mounted on the first mounting base 2651, meaning the third transmission head 2613 and the first transmission head can be mounted on the same mounting base 262. The third transmission head 2613 can be used to transmit electrical signals. Since the first transmission head is the first negative terminal, placing the third transmission head 2613 and the first transmission head on the same mounting base 262 avoids the risk of short circuits. Simultaneously, placing the third transmission head 2613 and the first transmission head on the same mounting base 262 improves the integration of the base station 20 and saves space in the docking structure 260.

[0179] The first transmission head may have a first center line extending vertically, and the third transmission head 2613 may have a second center line extending vertically. The first and second center lines may be staggered in the horizontal direction. This arrangement can prevent accidental contact during the horizontal placement of the handheld cleaning device in the groove structure, thus avoiding problems such as false triggering of signal communication and power supply.

[0180] The first and second center lines can be staggered vertically. This design prevents accidental contact when the handheld cleaning device is placed vertically in the recessed structure, which could lead to problems with signal communication and power supply mis-triggers.

[0181] Specifically, the distance between the third transmission head 2613 and the upper surface of the main body 210 can be greater than the distance between the first transmission head and the upper surface of the main body 210, meaning the third transmission head 2613 is positioned higher than the first transmission head. This arrangement prevents a short circuit between the third transmission head 2613 and the first transmission head due to water conduction on the base station 20. Furthermore, since the third transmission head 2613, which transmits electrical signals, is connected to an electrical signal source, and its first negative terminal is generally grounded, a short circuit will only occur when the water level on the base station 20 is above the third transmission head 2613, further reducing the probability of a short circuit in the third transmission head 2613.

[0182] The distance between the third transmission head 2613 and the upper surface of the main body 210 can be greater than or equal to 40mm and less than or equal to 70mm. Examples include 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, and 70mm. This arrangement ensures that the third transmission head 2613 has sufficient height to reduce the probability of a short circuit. It also avoids the problem of needing to increase the height of the third side portion 243 due to the third transmission head 2613 being set too high, thus reducing the overall height of the base station 20.

[0183] In some embodiments, such as Figures 22 to 25As shown, the cleaning base 10 includes a conductive element 150, which can be configured to transmit electrical energy and / or electrical signals. When the cleaning base 10 is placed on the base station 20, the conductive element 150 can dock with the docking structure of the base station 20. For example, the conductive element 150 can be electrically connected to the transmission head 261 to receive electrical energy and / or electrical signals transmitted by the transmission head 261 and transmit the electrical energy and / or electrical signals to components inside the handheld cleaning device. For example, the handheld cleaning device may include a battery and power-consuming components, and the conductive element 150 can transmit the electrical energy transmitted by the transmission head 261 to the battery and power-consuming components. The handheld cleaning device may also include a signal processor, and the conductive element 150 can transmit the electrical signals transmitted by the transmission head 261 to the signal processor, or the conductive element 150 can transmit the electrical signals emitted by the signal processor to the transmission head 261, and the transmission head 261 transmits the electrical signals to the processor inside the base station 20, thereby enabling signal interaction between the base station 20 and the handheld cleaning device.

[0184] The conductive element 150 can be rectangular, but is not limited thereto. The conductive element 150 can also be circular, triangular, etc. This disclosure does not impose specific restrictions on it.

[0185] The conductive component 150 can be disposed on the circumferential side of the base body 110 to facilitate electrical connection with the transmission head 261 disposed on the base station 20, eliminating the need for electrical connection on the top of the base station 20 and saving height space of the base body 110. It should be noted that the circumferential side of the base body 110 refers to the front, rear, left, and right sides of the base body 110 with the forward direction of the handheld cleaning device as the front. The forward direction of the handheld cleaning device refers to the direction of movement of the handheld cleaning device during the cleaning of the surface to be cleaned.

[0186] The conductive element 150 can be located on at least one side of the base body 110 in the second direction Y. In the horizontal plane, the second direction Y is perpendicular to the forward direction of the handheld cleaning device. It should be noted that, assuming the surface to be cleaned is flat, the horizontal plane can be parallel to the surface. This arrangement avoids the conductive element 150 occupying space in front of and behind the base body 110, thus preventing it from interfering with the cleaning operation of the base body 110.

[0187] In some embodiments, a receiving groove 170 may be provided on the circumferential side of the base body 110, and the conductive element 150 may be disposed on the bottom surface of the receiving groove 170. This arrangement provides a more stable mounting space for the conductive element 150 using the receiving groove 170, and the sidewalls of the receiving groove 170 protect the conductive element 150. Furthermore, when the conductive element 150 abuts against the transmission head 261, the sidewalls of the receiving groove 170 can limit the transmission head 261, preventing the conductive element 150 from disengaging from the transmission head 261 during electrical connection, thus ensuring the stability of power and / or signal transmission.

[0188] The sidewall of the receiving groove 170 can be inclined away from the center line extending along its depth direction of the receiving groove 170. With this configuration, the sidewall of the receiving groove 170 can be used to guide the transmission head 261, so as to ensure that the transmission head 261 can accurately enter the receiving groove 170 and make electrical connection with the conductive element 150.

[0189] The depth of the receiving groove 170 can be less than or equal to 3mm, such as 0.1mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. This setting can avoid the receiving groove 170 being too deep, thus saving the space occupied by the receiving groove 170.

[0190] The width of the receiving groove 170 can be greater than or equal to 5mm and less than or equal to 30mm. For example, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc. This setting ensures that the receiving groove 170 has sufficient width to accommodate the conductive component 150, and avoids the problem of excessive space occupied by the receiving groove 170 due to its excessive width.

[0191] The conductive element 150 can be positioned between the cleaning head 130 and the assist wheel 140 to avoid occupying the space designated for either the cleaning head 130 or the assist wheel 140. In the forward direction of the handheld cleaning device, the distance between the conductive element 150 and the cleaning head 130 can be greater than the distance between the conductive element 150 and the assist wheel 140. This arrangement keeps the conductive element 150 away from the cleaning head 130, preventing contamination from dirt on the surface to be cleaned or dirt picked up by the cleaning head 130, thus avoiding short circuits or poor contact issues with the conductive element 150.

[0192] Furthermore, the conductive element 150 can be disposed on the side of the base body 110 near the booster wheel 140. This arrangement can further increase the distance between the conductive element 150 and the cleaning head 130, further preventing dirt on the surface to be cleaned or dirt rolled up by the cleaning head 130 from contaminating the conductive element 150, and thus further preventing short circuits or poor contact problems of the conductive element 150.

[0193] In some embodiments, the base body 110 may also be provided with a clearance space 180, which may be disposed on the same side as the conductive element 150. This clearance space 180 may be close to the assist wheel 140 relative to the conductive element 150. This clearance space 180 may be used to avoid protruding structures on the base station 20, so that after the handheld cleaning device is placed on the base station 20, the protruding structure can be located within the clearance space 180, thus preventing the protruding structure from obstructing the electrical connection between the conductive element 150 and the transmission head 261. The protruding structure may be the aforementioned second guide wheel 252, but is not limited to it; it may also be other protruding structures on the base station 20.

[0194] Furthermore, the base body 110 may be provided with a clearance notch, which may be provided on the same side as the conductive component 150, and the clearance space 180 may be located within the clearance notch. However, it is not limited to this, the base body 110 may also be provided with a clearance groove, which may be provided on the same side as the conductive component 150, and the clearance space 180 may be located within the clearance groove.

[0195] In some embodiments, the handheld cleaning device may include a first conductive element (first charging terminal 151) and a second conductive element (second charging terminal 152). The first and second conductive elements may be spaced apart, and the first and second conductive elements may be used to transmit electrical energy and electrical signals, respectively. That is, one of the first and second conductive elements may be an electrode, and the other may be a signal transmission terminal. By spaced the first and second conductive elements apart, the distance between the electrode and the signal transmission terminal can be increased, avoiding the problem of short circuits between the electrode and the signal transmission terminal.

[0196] Furthermore, when the base station 20 includes a first transmission head and a second transmission head, the first conductive element can be correspondingly disposed with the first transmission head, and when the cleaning base 10 is placed in the groove structure, the first conductive element can abut against the first transmission head to achieve electrical connection. The second conductive element can be correspondingly disposed with the second transmission head, and when the cleaning base 10 is placed in the groove structure, the second conductive element can abut against the second transmission head to achieve electrical connection.

[0197] Furthermore, the first conductive element and the second conductive element can be located on opposite sides of the base body 110 in the second direction Y. This arrangement further distances the first conductive element from the second conductive element, further reducing the risk of a short circuit between the first and second conductive elements.

[0198] In some embodiments, the first conductive element can be a second negative electrode, and the second conductive element can be a second positive electrode. The distance between the first conductive element and the bottom surface of the base body 110 can be less than the distance between the second conductive element and the bottom surface of the base body 110.

[0199] The bottom surface of the base body 110 can be the side of the handheld cleaning device closest to the surface to be cleaned, where the first conductive element is positioned lower than the second conductive element. This arrangement prevents a short circuit between the first and second conductive elements due to water on the surface. Furthermore, since the second negative electrode is typically grounded, a short circuit only occurs when the water level on the surface is above the second conductive element, further reducing the probability of a short circuit at the second negative electrode.

[0200] The distance between the first conductive element and the bottom surface of the base body 110 can be greater than or equal to 10mm and less than or equal to 30mm. Examples include 10mm, 15mm, 20mm, 25mm, and 30mm. This arrangement avoids the first conductive element being too low and too close to the bottom surface of the base body 110, thus reducing the risk of short circuits when the first conductive element comes into contact with water on the surface to be cleaned. Simultaneously, it avoids the problem of the second conductive element needing to be set even higher if the first conductive element is set too high, further reducing the need for a higher base body 110 and ultimately lowering the overall height of the base body 110.

[0201] The distance between the second conductive component and the bottom surface of the base body 110 can be greater than or equal to 20mm and less than or equal to 60mm. For example, 20mm, 30mm, 40mm, 50mm, 60mm, etc. This setting ensures that the second conductive component has sufficient height to reduce the probability of a short circuit. Simultaneously, it avoids the problem of needing to increase the height of the base body 110 due to the second conductive component being set too high, thus reducing the overall height of the base body 110.

[0202] In some embodiments, the second docking structure 2602 may further include a third conductive element 153. The third conductive element 153 can be used to transmit electrical signals and can be spaced apart from the first conductive element and the second conductive element. This arrangement can increase the distance between the third conductive element 153 and the first and second conductive elements, reducing the probability of a short circuit between the third conductive element 153 and the first and second conductive elements.

[0203] When the base station 20 includes a third transmission head 2613, the third conductive element 153 can be configured correspondingly to the third transmission head 2613, and when the cleaning base 10 is placed in the groove structure, the third conductive element 153 abuts against the third transmission head 2613.

[0204] Furthermore, the third conductive element 153 can be located on a different side of the base body 110 from the second conductive element. Since the second conductive element is the second positive electrode, short circuits may occur if the third conductive element 153, which transmits electrical signals, and the second conductive element are located on the same side of the base body 110.

[0205] The third conductive element 153 and the first conductive element can be located on the same side of the base body 110. Since the first conductive element is the second negative electrode, placing the third conductive element 153, which transmits electrical signals, and the first conductive element on the same side of the base body 110 will not cause a short circuit risk. At the same time, placing the third conductive element 153 and the first conductive element on the same side of the base body 110 can improve the integration of the cleaning base 10 and save space in the base body 110.

[0206] The distance between the third conductive element 153 and the bottom surface of the base body 110 can be greater than the distance between the first conductive element and the upper surface of the main body 210, meaning the third conductive element 153 is positioned higher than the first conductive element. This arrangement prevents a short circuit between the third conductive element 153 and the first conductive element when there is water on the surface to be cleaned. Furthermore, since the third conductive element 153, which transmits electrical signals, is connected to an electrical signal source, and the second negative terminal is generally grounded, a short circuit will only occur when the water level on the surface to be cleaned does not exceed the third conductive element 153, further reducing the probability of a short circuit in the third conductive element 153.

[0207] The distance between the third conductive element 153 and the bottom surface of the base body 110 can be greater than or equal to 30mm and less than or equal to 60mm. For example, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, etc. This setting ensures that the third conductive element 153 has sufficient height to reduce the probability of a short circuit. Simultaneously, it avoids the problem of needing to raise the cleaning base 10 due to the third conductive element 153 being set too high, thus reducing the overall height of the cleaning base 10.

[0208] In some embodiments, the first conductive element has a first center point, and the third conductive element 153 has a second center point. The first center point and the second center point can be staggered in the forward direction of the handheld cleaning device. This arrangement allows the first conductive element and the third conductive element 153 to be staggered in the forward direction of the handheld cleaning device, avoiding the first conductive element from accidentally contacting the third transmission head 2613 during the process of the handheld cleaning device being pushed into or entering the groove structure on its own, which could lead to problems such as false triggering of signal communication and power supply.

[0209] The first center point and the second center point can be staggered in the height direction of the handheld cleaning device. This arrangement allows the first conductive element and the third conductive element 153 to be misaligned in the height direction, preventing the first conductive element from accidentally contacting the third transmission head 2613 during the placement of the handheld cleaning device in the groove structure along the height direction, which could lead to false triggering of signal communication and power supply.

[0210] In some embodiments, such as Figures 22 to 25 As shown, the handheld cleaning device may further include an electrical connector 160. The electrical connector 160 can be disposed on the base body 110, and can be disposed on the same side as the conductive element 150. The electrical connector 160 can also be located on the side of the conductive element 150 away from the base body 110. The electrical connector 160 is electrically connected to the conductive element 150 for transmitting electrical energy and / or electrical signals. It is understood that the electrical connector 160 can electrically connect the conductive element 150 and the electrical components and / or signal processor within the cleaning base 10 to further transmit the electrical energy and / or electrical signals transmitted by the conductive element 150 to the electrical components and / or signal processor. Simultaneously, by positioning the electrical connector 160 on the side of the conductive element 150 away from the base body 110, structural components such as the liquid supply tank 120 can be used to shield and protect the electrical connector 160, preventing it from coming into contact with liquids in the external environment and causing a short circuit.

[0211] The handheld cleaning device may include a first electrical connector 161 and a second electrical connector 162. The first electrical connector 161 may be electrically connected to a first conductive element for transmitting electrical energy and / or electrical signals transmitted by the first conductive element.

[0212] The first electrical connector 161 can be disposed on the same side as the first conductive member and can be located on the side of the first conductive member closer to the liquid supply tank 120. The second electrical connector 162 can be electrically connected to the second conductive member for transmitting electrical energy and / or electrical signals transmitted by the first conductive member. The second electrical connector 162 can be disposed on the same side as the second conductive member and can be located on the side of the second conductive member closer to the liquid supply tank 120.

[0213] The handheld cleaning device may further include a third electrical connector 163. The third electrical connector 163 may be electrically connected to the third conductive element 153 for transmitting electrical signals transmitted by the third conductive element 153.

[0214] The third electrical connector 163 can be disposed on the same side as the third conductive component 153 and located on the side of the third conductive component 153 closer to the liquid supply tank 120. There is a gap between the third electrical connector 163 and the second electrical connector 162 to avoid short circuit between the third electrical connector 163 and the second electrical connector 162.

[0215] The first electrical connector 161 may have a third center point, and the third electrical connector 163 may have a fourth center point. The third and fourth center points can be offset in the forward direction of the handheld cleaning device. This arrangement allows the first electrical connector 161 and the third electrical connector 163 to be staggered in the forward direction of the handheld cleaning device, saving space occupied by the first electrical connector 161 and the third electrical connector 163 and improving the space utilization of the base body 110. Simultaneously, it facilitates the connection of the first electrical connector 161 and the third electrical connector 163 to the circuit and reduces the risk of short circuits in the first electrical connector 161 and the third electrical connector 163.

[0216] The third and fourth center points can be staggered in the second direction Y. This arrangement allows the first electrical connector 161 and the third electrical connector 163 to be staggered in the second direction Y, saving space occupied by the first electrical connector 161 and the third electrical connector 163 and improving the space utilization of the base body 110. It also facilitates the connection of the first electrical connector 161 and the third electrical connector 163 to the circuit and reduces the risk of short circuits between the first electrical connector 161 and the third electrical connector 163.
