Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to a base station and a cleaning system. Background Technology

[0002] In the field of cleaning equipment technology, base stations are typically used to provide charging and storage functions for cleaning equipment. In related technologies, a base station includes a charging dock. The charging interface on the charging dock is generally separate from the positioning structure used to fix the cleaning equipment. Users need to place the cleaning equipment on the charging dock first, and then manually adjust it to align with the charging interface. This process is cumbersome and prone to poor charging contact due to inaccurate positioning. Summary of the Invention

[0003] In view of this, the embodiments of this application aim to provide a base station and a cleaning system to solve the problem of low charging reliability caused by the separation of charging and fixing of cleaning equipment in the prior art.

[0004] This application provides a base station, including a base for detachably placing a cleaning device, the cleaning device including a suction rod, the suction rod being provided with a mating part and a conductive part; The base includes a charging base, which has a first storage slot for accommodating part of the suction rod. The first storage slot is provided with a limiting structure and a first charging interface. The limiting structure is located in front of the first charging interface and is used to form a snap-fit ​​with the mating part. When the limiting structure is snap-fitted into place with the mating part, the conductive part is connected to the first charging interface for charging.

[0005] There is a cleaning device in the prior art that can replace the brush head of a floor scrubber or a vacuum cleaner. This device can be adapted to different usage scenarios. However, it is charged by setting a charging port on the brush head. This method requires setting a charging port on each brush head, which is very costly.

[0006] In this solution, the charging port is set on the suction rod, and the suction rod is provided with a mating part and a charging part. When the cleaning equipment is placed on the base station, it is connected to the base station by the mating part, and the charging action can be completed at the same time. In one embodiment, the charging part is set on the mating part. Therefore, when the mating part is engaged, it can both complete the charging and support the cleaning equipment.

[0007] In this solution, the base station sets a limiting structure on the wall of the first storage slot in front of the first charging interface. When the suction rod is inserted into the first storage slot, its mating part engages with the limiting structure, and at the same time, the conductive part automatically connects with the first charging interface to complete charging. This establishes a connection between positioning and charging, effectively simplifying the user's operation steps, avoiding the cumbersome alignment and poor charging contact problems caused by the separate design, and improving charging reliability and ease of use.

[0008] In one embodiment, the limiting structure is a limiting protrusion protruding from the wall of the first storage groove, and the mating part is a limiting slot corresponding to the protrusion.

[0009] In one embodiment, the limiting protrusion includes a protruding section and a snap-fit ​​section. One end of the protruding section protrudes onto the wall of the first receiving groove, and the other end of the protruding section is connected to the snap-fit ​​section. The width of the protruding section is smaller than the width of the snap-fit ​​section. The limiting slot includes a connected slot opening section and a slot cavity section, wherein the width of the slot opening section is smaller than the width of the slot cavity section. The limiting slot is inserted into the limiting structure from above, so that the locking segment engages with the slot cavity segment.

[0010] In one embodiment, the width of the snap-fit ​​segment gradually increases along the direction of the charging dock toward the base; The groove width of the cavity section is not less than the maximum width of the snap-fit ​​section.

[0011] In one embodiment, the limiting protrusion is flush with the side face of the cleaning device facing the same side face of the charging dock.

[0012] In one embodiment, the charging base is further provided with a second storage slot for accommodating part of the suction rod; the first storage slot and the second storage slot are located on opposite sides of the charging base; The second storage slot has a second charging interface on its wall, and the first charging interface is positioned opposite to the second charging interface. The cleaning device further includes a first cleaning attachment and a second cleaning attachment, and the suction rod is detachably connected to the first cleaning attachment or the second cleaning attachment; When the suction rod is connected to the first cleaning accessory and placed on the charging base, the conductive part is connected to the first charging interface for charging; when the suction rod is connected to the second cleaning accessory and placed on the charging base, the conductive part is connected to the second charging interface for charging.

[0013] In one embodiment, the first cleaning accessory is a floor cleaning head, and the second cleaning accessory is a vacuum cleaner head.

[0014] In one embodiment, the base is provided with a first accommodating position and a second accommodating position located on opposite sides of the charging base. The floor cleaning head can be placed in the first accommodating position, and the vacuum cleaner head can be placed in the second accommodating position. Both the first accommodating position and the second accommodating position are located to the side and below the charging dock.

[0015] In one embodiment, the cleaning device further includes a connector, one end of which is connected to the suction rod, and the other end of which is provided with the mating part; When the first cleaning attachment is placed in the first receiving position, and the suction rod rotates relative to the first cleaning attachment toward the charging base until the mating part engages with the limiting structure, the end face of the connector facing the charging base is closer to the charging base than the end face of the first cleaning attachment facing the charging base.

[0016] In one embodiment, the charging dock is provided with a circuit assembly, which includes a first circuit and a second circuit connected in parallel. The first circuit is electrically connected to the first charging interface, and the second circuit is electrically connected to the second charging interface.

[0017] In one embodiment, the conductive part is disposed on the mating part, and when the mating part is connected to the limiting structure, the conductive part is connected to the first charging interface for charging.

[0018] This application also provides a cleaning system, including a base station and a cleaning device detachably placed on the base station; The base station includes a base, the base includes a charging base, and a first charging interface and a second charging interface are respectively provided on opposite sides of the charging base; The cleaning device includes a suction rod, a first cleaning attachment, and a second cleaning attachment, wherein the suction rod is detachably connected to either the first cleaning attachment or the second cleaning attachment; The suction rod is provided with a conductive part; when the suction rod is connected to the first cleaning accessory, the conductive part is connected to the first charging interface for charging; when the suction rod is connected to the second cleaning accessory, the conductive part is connected to the second charging interface for charging.

[0019] In one embodiment, the first cleaning accessory is a floor cleaning head, and the second cleaning accessory is a vacuum cleaner head. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that in the description of this application, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] In the field of cleaning equipment technology, base stations are typically used to provide charging and storage functions for cleaning equipment. In related technologies, the charging dock of the base station separates the charging interface from the positioning structure of the cleaning equipment. This requires users to first place the cleaning equipment and then manually adjust it to align the charging interface, a cumbersome and inconsistent process that can easily lead to poor charging contact due to positioning errors. The root cause is that the charging function and the fixing function of cleaning accessories are handled by two independent components, lacking a connection and failing to automatically establish an electrical connection while the cleaning equipment is fixed. Furthermore, for the storage of accessories such as floor cleaning heads, most existing base stations rely solely on simple trays or recesses, lacking effective restraint structures. This makes floor cleaning heads prone to shaking, displacement, or even detachment when stored, affecting storage stability and failing to meet users' dual needs for convenient storage and stable charging.

[0031] To address the problems existing in related technologies, this application proposes a different technical approach. Its core concept lies in: by setting a limiting structure on the wall of the first storage slot of the charging base and positioning it in front of the first charging interface, the conductive part of the suction rod can only connect to the first charging interface for charging when it is engaged with the limiting structure. This associates the fixed positioning of the cleaning accessory (see below, where the cleaning accessory is the first cleaning accessory, i.e., the floor cleaning head) with electrical connection and charging. In other words, it provides a structure that links positioning and charging, solving the problems of unstable storage and low charging reliability caused by separate structures, achieving the technical effect of charging and stable storage without needing to consciously identify the orientation.

[0032] refer to Figures 1 to 5This application provides a base station 100 for placing and supporting cleaning equipment, and simultaneously charging the cleaning equipment. The base station 100 includes a base 101, which includes a charging base 102. The charging base 102 is a vertical portion extending upward from the base 101, and its interior can accommodate circuit components. The base 101, as a load-bearing foundation, can be made of injection-molded material and has a large bottom area to ensure stability during placement, stably supporting the cleaning equipment placed on it. The cleaning equipment can be a handheld floor scrubber detachably placed on the base station 100, including a suction rod 109, cleaning attachments (see below, here the cleaning attachments are a first cleaning attachment 108 or a second cleaning attachment 111) disposed at opposite ends of the suction rod 109, and a main unit assembly (not shown). The cleaning attachments (i.e., the first cleaning attachment 108 or the second cleaning attachment 111) are used to contact the ground for cleaning operations. The main unit assembly is located at the top of the suction rod 109 and includes a drive motor, a battery, and an electronic control module. The suction rod 109 is constructed as a hollow tube. Under the action of the drive motor, a negative pressure space is formed inside the suction rod 109 to achieve the suction of dirt (such as sewage, filth, dust, etc.). Most of the weight of the handheld floor scrubber is concentrated at the top of the suction rod 109, making the top counterweight of the handheld floor scrubber greater than the counterweight at the cleaning attachment (i.e., the first cleaning attachment 108 or the second cleaning attachment 111). In other words, the handheld floor scrubber has a "top-heavy" structure and cannot be placed upright when the whole machine is detached from external support.

[0033] The suction rod 109 is provided with a mating part 105 and a conductive part (not shown). The mating part 105 is used to form a snap-fit ​​engagement with the limiting structure 104 on the base station 100, and the conductive part is used to electrically connect with the first charging interface 106 on the base station 100 to receive charging current. The conductive part can be a conductive contact or electrode plate exposed on the surface of the suction rod 109, and is electrically connected to the battery inside the cleaning device. For example, a wire electrically connected to the conductive part can be provided inside the suction rod 109 to transmit the charging current to the battery. The charging base 102 has a first storage groove 103, which is a recess with an opening. Its shape and size are configured to accommodate at least a portion of the length of the suction rod 109, so that the suction rod 109 can be inserted into the first storage groove 103 from top to bottom in a generally vertical direction. A limiting structure 104 and a first charging interface 106 are provided on the side wall of the first storage slot 103. The limiting structure 104 is located in front of the first charging interface 106 and is configured to engage with the mating part 105 on the suction rod 109, thereby restricting the suction rod 109 from being pulled out after it is inserted into place, and also restricting the movement of the cleaning accessory (i.e., the first cleaning accessory 108), preventing the cleaning equipment from accidentally coming loose in the stored state, and thus fixing the cleaning accessory (i.e., the first cleaning accessory 108). The first charging interface 106 includes conductive terminals and can be implemented in the form of a spring pin connector, etc., and its electrical circuit is connected to the power circuit inside the base station 100. For example, in one example, the first charging interface 106 includes multiple contacts (e.g., three). When the limiting structure 104 and the mating part 105 are engaged, the conductive part on the suction rod 109 is precisely aligned with the contacts of the first charging interface 106 and forms an electrical connection, thereby enabling the charging of the cleaning equipment.

[0034] When the user inserts the suction rod 109 into the first storage slot 103 from top to bottom, the mating part 105 slides past the first charging port 106 and engages with the limiting structure 104 below it. At this time, the conductive part just contacts the first charging port 106, thus completing the positioning and charging docking simultaneously. In this way, by arranging the limiting structure 104 in front of the first charging port 106 within the same first storage slot 103, gravity is used to assist insertion and engagement. At the same time, it automatically aligns for charging when engaged, avoiding the additional alignment steps and charging failure risks caused by the separate positioning and charging port settings in related technologies.

[0035] In this solution, by staggering the limiting structure 104 and the first charging interface 106 in the same first storage slot 103 along the vertical direction, and with the limiting structure 104 positioned in front of the first charging interface 106, the suction rod 109, during insertion into the first storage slot 103, simultaneously engages with the limiting structure 104 at its mating part 105, and the conductive part automatically connects with the first charging interface 106 for charging. This means that the insertion action itself simultaneously secures and electrically connects the cleaning device, eliminating the need for additional alignment or locking operations. This establishes a connection between positioning, fixing, and charging, effectively simplifying user operation steps and avoiding the cumbersome alignment and poor charging contact issues caused by the separate design, thus improving charging reliability and ease of use.

[0036] In an alternative embodiment, the limiting structure 104 may also be a resiliently resettable claw disposed on the wall of the first storage groove 103, with the mating part 105 corresponding to a card hole; or the limiting structure 104 may be a magnetic element, with the mating part 105 being a attracted ferromagnetic element, in which case the magnetic attraction provides both fixing force and electrical connection function.

[0037] To achieve reliable mechanical engagement with a relatively simple structure, the limiting structure 104 can be a protrusion, and the mating part 105 can be a groove. (Reference) Figure 1 , Figure 2 and Figure 6 and combined Figures 3 to 5 In one embodiment, the limiting structure 104 is a limiting protrusion protruding from the wall of the first receiving groove 103, and the mating part 105 is a limiting groove corresponding to the protrusion. The limiting protrusion can be a block protruding from the groove wall into the groove space, and the limiting groove is a recessed area. The contours of the limiting protrusion and the limiting groove match each other. When the suction rod 109 is inserted into place, the limiting protrusion is precisely engaged in the limiting groove to form a barrier and prevent the suction rod 109 from accidentally coming out. This concave-convex fitting structure can be directly integrally molded by injection molding process without the need to add separate fasteners, reducing the number of parts and assembly costs.

[0038] Both the aforementioned limiting protrusion and limiting slot have an extension dimension along the depth direction of the first receiving groove 103, ensuring that the engagement depth is sufficient to limit accidental movement of the cleaning device, and that the contact surfaces of both can withstand pull-out force. The shape of the limiting protrusion can be rectangular, trapezoidal, or T-shaped, as long as it can be embedded in the limiting slot and form reliable interference. Through a simple convex-concave fit, not only is the effect of preventing the suction rod 109 from swaying back and forth or left and right during storage achieved, but the vertical engagement also helps to stably support the cleaning device on the base station 100, avoiding loosening caused by the weight of the cleaning device or external forces.

[0039] In another feasible implementation, the positions of the limiting protrusion and the limiting slot can be interchanged. That is, the limiting protrusion is set on the suction rod 109, and the limiting slot is set on the wall of the first storage slot 103, which can also form a snap-fit ​​engagement.

[0040] Based on the combination of a limiting protrusion and a limiting slot, to achieve a more reliable anti-detachment effect without additional locking components, the limiting protrusion can be constructed with a structure having varying widths, and the limiting slot can be constructed with a cavity structure having corresponding width variations. (Reference) Figure 1 , Figure 2 and Figure 6 and combined Figures 3 to 5 The limiting protrusion includes a protruding section 114 and a snap-fit ​​section 115. One end of the protruding section 114 protrudes from the wall of the first receiving groove 103, and the other end of the protruding section 114 is connected to the snap-fit ​​section 115. The width of the protruding section 114 is smaller than the width of the snap-fit ​​section 115. The limiting slot includes a connected slot opening section 116 and a slot cavity section 117. The width of the slot opening section 116 is smaller than the width of the slot cavity section 117. The limiting slot is inserted into the limiting structure 104 from above, so that the snap-fit ​​section 115 snaps into the slot cavity section 117.

[0041] The cross-section of the limiting protrusion is roughly T-shaped. The protrusion section 114 refers to the part directly connected to the groove wall, and its cross-sectional width is relatively narrow. The locking section 115 is the enlarged portion located at the free end of the protrusion section 114, and its width is greater than that of the protrusion section 114. The groove opening section 116 is the entrance portion of the limiting groove, and its width is narrower, matching or slightly larger than the width of the protrusion section 114. The groove cavity section 117 is the area that widens after extending inward from the groove opening section 116, and its width is sufficient to accommodate the locking section 115. When the suction rod 109 is inserted downwards, the limiting slot fits onto the limiting protrusion from above. The narrower slot section 116 enters the protrusion section 114, and the wider locking section 115 enters the wider cavity section 117. At this time, because the width of the locking section 115 is greater than the width of the slot section 116, and the groove wall of the cavity section 117 blocks the locking section 115, the locking section 115 is blocked in the front-back and left-right directions. At the same time, the gravity of the suction rod 109 can effectively resist the unexpected upward pull-out force. The limiting in this embodiment does not rely on friction, nor does it require an additional elastic arm or lock. It only achieves anti-dislodgement through the shape containment when the part is inserted, and the structure is simple.

[0042] This variable-width snap-fit ​​structure allows the suction rod 109 to effectively resist upward pulling or vibration of the cleaning equipment, preventing it from being pulled upwards. Furthermore, the four sides of the snap-fit ​​section 115 contact the cavity wall of the slot section 117, forming a surface contact barrier. Since the width of the snap-fit ​​section 115 is greater than the width of the slot section 116, it also cannot detach from the slot section 116, thus providing a resistance force far greater than simple friction. Simultaneously, because insertion is from top to bottom, the slot section 117 can slide in with the aid of gravity during the fitting process of the snap-fit ​​section 115, resulting in a smoother operation.

[0043] To provide guidance during insertion and ensure a tighter fit after the card is in place, reducing wobbling gaps, the width of the card segment 115 can be configured to gradually change along a specific direction. (Reference) Figure 1 , Figure 2 and Figure 6 and combined Figures 3 to 5 In one embodiment, the width of the latching segment 115 gradually increases along the direction of the charging base 102 towards the base 101; the width of the slot segment 117 is not less than the maximum width of the latching segment 115. Here, the direction of the charging base 102 towards the base 101 can be understood as the direction from the upper end of the charging base 102 towards the base 101, that is, the direction approximately downward. The latching segment 115 gradually increases in width in the downward direction, forming a wedge shape, so that the limiting slot will not collide with the limiting protrusion when it is about to be fitted into the limiting protrusion, and can be smoothly fitted into the limiting protrusion. When the limiting slot is fitted into the limiting protrusion from top to bottom, the side slope of the latching segment 115 plays a guiding role, making the insertion process smooth and effortless. The width of the groove section 117 is at least equal to the maximum width of the snap-fit ​​section 115, ensuring that when the snap-fit ​​section 115 is fully inserted into the groove section 117, the maximum width of the snap-fit ​​section can make close contact with the side wall of the groove section 117 or leave a small gap. Both of these achieve precise positioning after snap-fitting, reducing the left and right swing amplitude of the suction rod 109 in the snap-fit ​​state, thereby reducing noise and wear caused by the fit gap.

[0044] The gradually increasing width gradient of the snap-fit ​​segment 115 can be set as needed, such as linearly or curvilinearly, resulting in better guiding effect. The slot width of the cavity segment 117 can be equal to or slightly larger than the maximum width of the snap-fit ​​segment 115, ensuring smooth insertion while controlling wobbling, so that the snap-fit ​​segment 115 can be accurately positioned within the cavity segment 117 after insertion. If the slot width of the cavity segment 117 is less than the maximum width of the snap-fit ​​segment 115, it will result in incomplete insertion or jamming; if the slot width of the cavity segment 117 is much larger than the maximum width of the snap-fit ​​segment 115, it will cause significant wobbling of the snap-fit ​​segment 115 within the cavity segment 117, reducing the fixing effect.

[0045] refer to Figure 1In one embodiment, to provide a sufficiently strong limiting protrusion within the limited space of the first storage slot 103, while avoiding excessive occupation of the channel space within the first storage slot 103 by the limiting protrusion and affecting the smooth sliding of the suction rod 109, the end face of the limiting protrusion facing the cleaning device can be flush with the same end face of the charging base 102. Specifically, the limiting protrusion has an end face facing the cleaning device (i.e., facing the inserted suction rod 109), and the end face of the limiting protrusion and the same end face of the charging base 102 are in the same plane. In other words, the limiting protrusion does not protrude beyond the end face of the charging base 102 where the first storage slot 103 is located, but is flush with that end face of the charging base 102. In this way, while ensuring that the limiting protrusion has sufficient protrusion length to achieve a reliable snap-fit, it will not occupy additional space within the first storage slot 103, keeping the opening area of ​​the first storage slot 103 unobstructed, allowing the suction rod 109 to slide in without obstruction. At the same time, the flush surface reduces dust accumulation dead spots, making cleaning and maintenance easier, and simplifies the mold structure during injection molding, which helps to reduce manufacturing difficulty and cost.

[0046] Alternatively, the limiting protrusion can be slightly recessed into the first storage groove 103, that is, recessed inward by a small distance, or slightly protruding from the side end face of the charging base 102 where the first storage groove 103 is provided, as long as it does not affect the insertion and removal action.

[0047] In the field of cleaning equipment technology, to improve cleaning efficiency and ease of use, some cleaning devices are equipped with two different cleaning attachments. Typically, cleaning devices connected to different attachments (such as floor scrubbing heads and vacuum cleaner heads) need to be charged to maintain their usability. In related technologies, most base station charging docks have only one charging port, and the base station is only compatible with one type of cleaning attachment. When users alternate between different types of cleaning attachments, they must switch to a specific attachment for charging, increasing the number of steps and inconvenience for users.

[0048] This application aims to enable the base station 100 to be compatible with cleaning equipment having two different cleaning attachments, so that regardless of which cleaning attachment is used, the suction rod 109 can be connected to the charging interface of the base station 100 for charging without changing the cleaning attachment. (Reference) Figure 1 and Figure 2 and combined Figures 3 to 5In one embodiment, the charging base 102 is further provided with a second storage slot 112 for accommodating a portion of the suction rod 109. The first storage slot 103 and the second storage slot 112 are located on opposite sides of the charging base 102. A second charging interface 110 is provided on the wall of the second storage slot 112, and the first charging interface 106 is disposed opposite to the second charging interface 110. The cleaning device also includes a first cleaning attachment 108 and a second cleaning attachment 111, and the suction rod 109 is detachably connected to either the first cleaning attachment 108 or the second cleaning attachment 111. When the suction rod 109 is connected to the first cleaning attachment 108 and placed on the charging base 102, its conductive part is connected to the first charging interface 106 for charging; when the suction rod 109 is connected to the second cleaning attachment 111 and placed on the charging base 102, its conductive part is connected to the second charging interface 110 for charging.

[0049] In this embodiment, the structure of the second storage slot 112 can be the same as or symmetrical to the first storage slot 103. It also has a corresponding limiting member (forming a snap-fit ​​with the mating part 105, charging when snapped in place) and a second charging interface 110. Its limiting member snaps into the mating part 105 on the suction rod 109, which will not be described in detail here. The first charging interface 106 and the second charging interface 110 are located on the two side walls of the charging base 102 and are opposite to each other. This means that when the suction rod 109 is placed into the storage slot on the corresponding side, its conductive part connects to the charging interface on that side. The first cleaning attachment 108 and the second cleaning attachment 111 can be cleaning heads with different functions, both of which can be detachably connected to the lower end of the suction rod 109. When the user connects the suction rod 109 to the first cleaning attachment 108 and places the entire cleaning device on the base station 100, the suction rod 109 is placed into the first storage slot 103, and its conductive part connects to the first charging interface 106 for charging. When the suction rod 109 and the second cleaning attachment 111 are replaced, the cleaning device is reversed and placed in the second storage slot 112, with the conductive part connecting to the second charging port 110 for charging. This eliminates the need to replace the device with a specific cleaning attachment for charging and also enables instant charging from both sides.

[0050] This dual-sided charging interface design effectively utilizes the three-dimensional space of the charging base 102, allowing a single suction rod 109 and the base station 100 to be compatible with the charging needs of two different cleaning accessories, eliminating the hassle of users having to replace specific cleaning accessories. Simultaneously, the dual-sided storage slots provide both sides of the suction rod 109 for containment and fixation, ensuring that the suction rod 109 is securely positioned regardless of the cleaning accessory used.

[0051] In another embodiment, the other two sides of the charging dock 102 may also have storage slots and charging ports to accommodate more accessories.

[0052] Based on the dual-sided charging capability, the first cleaning accessory 108 can specifically be a floor cleaning head, and the second cleaning accessory 111 can specifically be a vacuum cleaner head. The floor cleaning head typically includes a rotating roller brush, a water spray mechanism, and a wastewater recovery structure, and is used for wet floor cleaning. The vacuum cleaner head typically includes a suction inlet and a roller brush, and is used for dry vacuuming. These two cleaning accessories have different functions and may come into contact with water during operation. Therefore, it is desirable to spatially separate the wet and dry accessories during storage and charging to prevent moisture from entering the charging interface. By designating the first cleaning accessory 108 as a floor cleaning head and the second cleaning accessory 111 as a vacuum cleaner head, and using dual-sided storage slots, the wet floor cleaning head and the dry vacuum cleaner head are guided to their respective sides of the charging base 102, with their corresponding charging interfaces being relatively independent, thereby reducing the risk of moisture intrusion damaging the circuitry.

[0053] Of course, the types of the first cleaning attachment 108 and the second cleaning attachment 111 are not limited to the two types mentioned above. They can also be an electric mop head and a mite removal suction head, or a combination of the cleaning attachments mentioned above.

[0054] To neatly place the two cleaning accessories without increasing the overall horizontal footprint of the base station 100 and to avoid interfering with the path of the suction rod 109 into the charging base 102, receiving positions can be provided on the base 101 on opposite sides of the charging base 102. (Reference) Figure 1 and Figure 2 and combined Figures 3 to 5 In one embodiment, the base 101 is provided with a first accommodating position 118 and a second accommodating position 119 located on opposite sides of the charging base 102. A floor cleaning head can be placed in the first accommodating position 118, and a vacuum cleaner head can be placed in the second accommodating position 119. The first accommodating position 118 and the second accommodating position 119 are both located to the side and below the charging base 102.

[0055] The first receiving position 118 and the second receiving position 119 can be recessed areas or platform areas on the upper surface of the base 101, respectively arranged on the left and right sides of the charging base 102, facing downwards. They can be trays extending outwards from the side wall of the charging base 102, as long as their height is lower than the storage slot. When the floor cleaning head is connected to the suction rod 109, it can be placed in the first receiving position 118, at which time the floor cleaning head is located on the lower left side of the charging base 102; when the vacuum cleaner head is used, the vacuum cleaner head is placed in the second receiving position 119, located on the lower right side of the charging base 102. Since the storage slots on both sides of the charging base 102 are located in the upper area of ​​the charging base, while the cleaning attachments are located on the lower side of the charging base 102 and are staggered in height, when the suction rod 109 is inserted downward into the storage slot, the cleaning attachment connected to its lower end is already in the corresponding receiving position and will not collide with the side wall of the charging base 102. This also avoids the cleaning attachments blocking the insertion path of the suction rod 109, making the operation smoother.

[0056] This layout in this embodiment gives the base station 100 a symmetrical shape, wider at the bottom and narrower at the top, resulting in a low center of gravity and enhanced placement stability. It also provides natural positioning guidance for switching between dual-sided charging; users can simply place the cleaning equipment on the corresponding side according to the cleaning accessories they use.

[0057] refer to Figure 3 Because the conductive part on the suction rod 109 cannot connect to the charging interface for charging after the cleaning accessory is placed in the corresponding receiving position, and the mating part 105 cannot engage with the limiting structure 104, this solution includes a connector 113. (Reference) Figures 3 to 6 In one embodiment, the cleaning device further includes a connector 113, one end of which is connected to the suction rod 109, and the other end is provided with a mating part 105. When the first cleaning attachment 108 is placed on the first receiving position 118, and the suction rod 109 rotates relative to the first cleaning attachment 108 toward the charging base 102 until the mating part 105 engages with the limiting structure 104, the end face of the connector 113 toward the charging base 102 is closer to the charging base 102 than the end face of the first cleaning attachment 108 toward the charging base 102.

[0058] The connector 113 is a transitional member connected to the lower end of the suction rod 109. It can be made of plastic or metal, and its end away from the suction rod 109 has a mating part 105 for engaging with the limiting structure 104. With the cleaning attachment already placed in the receiving position, the suction rod 109, together with the connector 113, rotates around the upper hinge of the cleaning attachment toward the charging base 102 until the mating part 105 engages with the limiting structure 104. During this rotation, the end face of the connector 113 facing the charging base 102 protrudes more than the same-side end face of the first cleaning attachment 108, meaning that the connector 113 is closer to the charging base 102 in the direction toward the charging base 102.

[0059] By setting a connector 113, with one end connected to the suction rod 109 and the other end fitted with a mating part 105, and by positioning the end face of the connector 113 facing the charging base 102 closer to the charging base 102 than the end face of the first cleaning accessory 108 facing the charging base 102, when the suction rod 109 rotates and engages with the first cleaning accessory 108 towards the charging base 102, the connector 113 can first approach the charging base 102 and guide the mating part 105 to accurately engage with the limiting structure 104. This allows the conductive part on the suction rod 109 to reliably connect with the first charging interface 106, eliminating the need for the user to manually adjust the angle or position of the suction rod 109, thus improving the convenience and success rate of the charging operation. Furthermore, this design ensures that even if the cleaning accessory is large, there is sufficient space below the storage slot for the rotation and positioning of the suction rod 109, guaranteeing the smoothness and reliability of the storage operation.

[0060] The connector 113 can be an integrally injection-molded support arm with the suction rod 109, or it can be a separate part that is sleeved on. The mating part 105 on the connector 113 can be a limiting groove as described above or other forms of mating structure. In another embodiment, the connector 113 can also be a telescopic sleeve to accommodate the height differences of different cleaning attachments.

[0061] To supply power to the first charging port 106 and the second charging port 110 on both sides of the charging dock 102 with a simplified circuit architecture, a parallel circuit can be installed inside the charging dock 102. (Reference) Figure 1 In one embodiment, the charging dock 102 is provided with a circuit assembly (not shown), which includes a first circuit and a second circuit connected in parallel. The first circuit is electrically connected to the first charging interface 106, and the second circuit is electrically connected to the second charging interface 110.

[0062] The circuit assembly includes positive and negative conductors and signal lines, branching from the power input terminal into two parallel branches, defined as the first circuit and the second circuit, respectively. The output terminal of the first circuit is connected to the contacts of the first charging interface 106, and the output terminal of the second circuit is connected to the contacts of the second charging interface 110. Parallel connection means that both charging interfaces share the same input voltage and can both provide charging current to the connected conductive parts. When only one charging interface is charging the cleaning device, current flows through the circuit on that side; when both charging interfaces are charging the cleaning device (for example, for a cleaning device with the battery mounted on a cleaning attachment, each cleaning attachment can be connected to a suction rod 109 to achieve simultaneous charging on both sides), the parallel circuit supplies power to both sides simultaneously, but independently, without interfering with each other.

[0063] The use of parallel circuits allows the base station 100 to support dual-sided charging with only one input power line, resulting in a simple internal layout.

[0064] See Figure 1 , Figure 2 and Figure 6 In one embodiment, the conductive part is disposed on the mating part 105. When the mating part 105 is connected to the limiting structure 104, the conductive part is connected to the first charging interface 106 for charging.

[0065] In this embodiment, to further simplify the structure and improve the reliability of charging docking, the conductive part is disposed on the mating part 105. Specifically, the mating part 105 can be a limiting groove disposed on the suction rod 109, at least a portion of the surface of the limiting groove is made of conductive material or has conductive contacts or electrode plates thereon, thereby constituting a conductive part. The first charging interface 106 is disposed on the groove wall of the first receiving groove 103, and its position corresponds to the limiting structure 104. When the suction rod 109 is inserted into the first receiving groove 103, the mating part 105 (i.e., the limiting groove) passes from top to bottom through the limiting structure 104 until it is engaged with the limiting structure 104. At this time, the conductive part located on the mating part 105 is precisely aligned with the conductive terminal of the first charging interface 106 in position and angle and forms a tight contact, thereby establishing an electrical connection and realizing the charging of the cleaning equipment.

[0066] By placing the conductive part on the mating part 105, the mating part 105 achieves both mechanical engagement and electrical connection. After the suction rod 109 is inserted into the first storage slot 103, when the mating part 105 and the limiting structure 104 are engaged, the conductive part automatically connects to the first charging interface 106 for charging. Simultaneously, the mechanical pressure generated during engagement ensures a tight and reliable contact between the conductive part and the first charging interface 106, preventing charging interruptions due to vibration or loosening, and effectively improving charging stability and anti-interference capabilities.

[0067] refer to Figures 1 to 5 This application also provides a cleaning system, including a base station 100 and a cleaning device detachably placed on the base station 100. The base station 100 includes a base 101, which includes an upwardly extending charging base 102. A first charging interface 106 and a second charging interface 110 are respectively provided on opposite sides of the charging base 102. The cleaning device includes a suction rod 109, a first cleaning attachment 108, and a second cleaning attachment 111. The suction rod 109 is detachably connected to either the first cleaning attachment 108 or the second cleaning attachment 111. A conductive portion is provided on the suction rod 109. When the suction rod 109 is connected to the first cleaning attachment 108, the conductive portion is connected to the first charging interface 106 for charging; when the suction rod 109 is connected to the second cleaning attachment 111, the conductive portion is connected to the second charging interface 110 for charging.

[0068] The cleaning system features charging ports on both sides, allowing the cleaning device to be placed directly and stably on the base station 100 for charging, regardless of the type of cleaning accessory connected, without needing to be replaced with a specific cleaning accessory. It also enables simultaneous charging from both sides.

[0069] The first charging port 106 is located in the storage groove formed on the left side wall of the charging base 102, and the second charging port 110 is located in the storage groove formed on the right side wall of the charging base 102. When the cleaning device is using the first cleaning accessory 108, the cleaning device is placed on the base 101, and its suction rod 109 enters the storage groove on the left side, so that the conductive part is naturally aligned with the first charging port 106 for charging. When the second cleaning accessory 111 is used, the cleaning device is placed on the base 101, and its suction rod 109 enters the storage groove on the right side, so that the conductive part is aligned with the second charging port 110 for charging.

[0070] Thus, with a single suction rod 109 equipped with dual cleaning attachments, the cleaning system provides dual-sided charging capability, significantly improving the flexibility of the cleaning equipment. At the same time, compared to the traditional solution with only one fixed charging port, users can directly place any cleaning attachment on the base station 100 for charging without having to switch to a specific cleaning attachment, making charging more convenient and faster, and improving the user experience.

[0071] refer to Figures 1 to 5 In one embodiment, the first cleaning accessory 108 is a floor cleaning head, and the second cleaning accessory 111 is a vacuum cleaner head. The floor cleaning head is used for wet mopping the floor, and the vacuum cleaner head is used for vacuuming up dry debris.

[0072] By pairing the dual-sided charging structure with these two cleaning attachments, which have different functions, the cleaning system can seamlessly switch between wet mopping and dry vacuuming modes and charge them separately. This also prevents residual moisture from the wet floor cleaning head from entering the charging port near the dry vacuum head, improving electrical safety. The floor cleaning head and vacuum head are placed in their corresponding positions on either side of the charging base 102 for dual-sided charging. In daily use, users simply need to change the attachment according to their cleaning needs and place the cleaning equipment on the corresponding side of the base station 100 for secure fixing and automatic charging; the operation is extremely convenient.

[0073] It is understood that other structures on the base station 100, as well as receiving slots, limiting components, etc., can adopt the limitations of the above embodiments, or can be set according to actual needs, and will not be described in detail here.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications or equivalent substitutions made within the spirit and principles of this application should be included within the protection scope of this application.
