Description

Technical Field

[0001] This disclosure belongs to the field of household cleaning equipment technology, specifically relating to a cleaning base station and a cleaning system. Background Technology

[0002] Cleaning stations are typically equipped with a waste collection unit. When cleaning equipment stops at a cleaning station, the waste in the dust cup of the cleaning equipment is transferred to the waste collection box for centralized processing.

[0003] In related technologies, in order to achieve multiple cleaning methods, various cleaning devices (such as vacuum cleaners and floor scrubbers) are usually set up in the cleaning base station. This results in the cleaning base station needing to be equipped with a separate dirt collection box for each of the various cleaning devices, which increases the number of accessories for the cleaning base station.

[0037] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0038] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0039] According to the first aspect of this disclosure, referring to Figure 1 This disclosure provides a cleaning base station 1, including a dirt collection component 11 and a floor washing component 12.

[0040] In some embodiments, in conjunction with reference Figure 2 As shown, the dirt collection assembly 11 includes a dirt collection box 111 and a dust collection duct 112. The dirt collection box 111 has a dirt collection chamber 1111 and a dust collection port 1112.

[0041] In some embodiments, in conjunction with reference Figure 3 As shown, the floor cleaning assembly 12 includes a floor cleaning brush 121 and a suction pipe 122.

[0042] In some embodiments, in conjunction with reference Figure 4 As shown, the cleaning base station 1 has a dust collection mode. In the dust collection mode, the dust collection port 1112, the dirt collection chamber 1111, and the dust collection air duct 112 are connected along the airflow direction.

[0043] In this embodiment, in the dust collection mode, the dust collection port 1112 serves as the inlet for dry waste. Dust and other debris in the cleaning equipment are sucked into the sludge collection chamber 1111 for dust-air separation, and the separated airflow is discharged through the dust collection duct 112.

[0044] In some embodiments, in conjunction with reference Figure 5As shown, the cleaning base station 1 also has a floor washing mode. In the floor washing mode, the floor washing brush 121, the suction pipe 122, and the collection chamber 1111 are connected along the airflow direction.

[0045] In this embodiment, in the floor cleaning mode, the water-containing airflow generated by the floor cleaning brush 121 cleaning the surface to be cleaned (e.g., a roller brush or the ground) enters the same collection chamber 1111 through the suction pipe 122 for water-air separation.

[0046] In this embodiment, by reusing the collection chamber 1111 of the sludge collection box 111 as a common chamber for dust and gas separation and water and gas separation, and by adding the floor washing component 12, the cleaning base station 1 is made multi-functional, which improves the space utilization and usage frequency of the cleaning base station 1 and reduces the overall usage cost for users.

[0047] In this embodiment, by adding a floor-washing component 12 to the dirt collection component 11, the cleaning base station 1 integrates both dust collection and self-cleaning functions. This not only increases the frequency of use of the cleaning base station 1 in daily life (it can both empty dust and clean), but also reduces the number and cost of additional floor-washing accessories that users need to purchase, saving indoor storage space.

[0048] Thus, in dust collection mode, the dust-laden airflow inside the cleaning equipment can flow into the dirt collection chamber 1111 through the dust collection port 1112, and in floor washing mode, the water-laden airflow drawn by the floor washing brush 121 can flow into the dirt collection chamber 1111 through the suction pipe 122. This allows the cleaning base station 1 to share a single dirt collection box 111 in both dust collection and floor washing modes, reducing the number of accessories for the cleaning base station 1.

[0049] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, the dust collection duct 112 is connected to the negative pressure source.

[0050] In some embodiments, continue to refer to Figure 5 As shown, the sludge collection assembly 11 also includes an exhaust connector 113, which connects the sludge collection chamber 1111 to a negative pressure source during the floor cleaning mode.

[0051] In this embodiment, the sludge collection chamber 1111 is connected to the same negative pressure source through the exhaust connector 113, so that the dust collection mode and the floor washing mode share a set of power systems, which simplifies the structure of the cleaning base station 1, reduces manufacturing costs, and avoids the redundant design of setting up a separate fan for the floor washing function.

[0052] For example, a negative pressure source (e.g., a negative pressure fan) is provided inside the cleaning base station 1 or the cleaning equipment that interfaces with the cleaning base station 1. The exhaust connector 113 is used to connect the dirt collection chamber 1111 to the negative pressure source in the floor washing mode.

[0053] Specifically, in dust collection mode, the negative pressure source draws air from the dirt collection chamber 1111 through the dust collection duct 112, while the exhaust connector 113 is in a non-operating state (e.g., closed or blocked). In floor cleaning mode, the dust collection duct 112 is closed or switched, while the exhaust connector 113 is opened and connected to the negative pressure source, allowing the negative pressure source to draw air from the dirt collection chamber 1111 through the exhaust connector 113, thereby creating the negative pressure airflow required for floor cleaning within the dirt collection chamber 1111. With this design, both modes share the same negative pressure source, eliminating the need for a separate negative pressure fan for the floor cleaning function and effectively simplifying the power structure of the cleaning base station 1 or the cleaning system.

[0054] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, the exhaust connector 113 is housed within the outer contour of the dust collection box 111.

[0055] In this embodiment, the exhaust connector 113 is housed within the outer contour of the sludge collection box 111 in the dust collection mode, without occupying additional space and avoiding physical interference with the parked cleaning equipment.

[0056] In some embodiments, continue to refer to Figure 5 As shown, in the floor cleaning mode, the exhaust connector 113 protrudes beyond the outer contour of the sludge collection box 111.

[0057] In this embodiment, during the floor cleaning mode, the exhaust connector 113 protrudes beyond the outer contour of the sludge collection box 111 (e.g., the outer wall of the sludge collection box 111), which facilitates quick connection with the air circuit interface of the cleaning equipment or other external pipelines, making operation convenient.

[0058] In some embodiments, continue to refer to Figure 4 and Figure 5 As shown, the vent connector 113 is pivotally connected to the sludge collection box 111.

[0059] In this embodiment, the exhaust connector 113 and the sludge collection box 111 are pivotally connected (e.g., a flipping structure). Users only need to flip the exhaust connector 113 to switch its position without disassembling parts. The structure is simple and reliable, and the user experience is good.

[0060] For example, one end of the exhaust connector 113 can be hinged to the side wall opening of the sludge collection box 111 via a pivot. In dust collection mode, the exhaust connector 113 flips inward around the pivot axis, so that it is entirely housed within the outer contour of the sludge collection box 111 (e.g., close to the side wall of the sludge collection box 111), thus preventing interference with the cleaning equipment handle or body parked on the cleaning base station 1. When switching to floor washing mode, the user or drive mechanism can flip the exhaust connector 113 outward, so that its free end protrudes from the outer wall of the sludge collection box 111. At this time, the interface of the exhaust connector 113 faces the air inlet pipe of the cleaning equipment handheld assembly, facilitating docking between the two. This flipping structure is intuitive to operate and allows for state switching without tools.

[0061] In some embodiments, continue to refer to Figure 1 As shown, the dirt collection assembly 11 is detachably connected to the floor cleaning assembly 121.

[0062] In this embodiment, the sludge collection component 11 and the floor cleaning component 121 are detachably connected, which makes it convenient for users to remove the sludge collection box 111 separately to empty sewage or dry garbage, and facilitates deep cleaning of the inside of the sludge collection chamber 1111 for more thorough maintenance.

[0063] For example, to facilitate independent cleaning of the waste collection bin 111 by the user, the waste collection assembly 11 and the floor cleaning assembly 12 are detachably connected. For instance, the bottom of the waste collection bin 111 is provided with a buckle or a sliding groove, and the floor cleaning assembly 12 is provided with a corresponding slot or guide rail. The user can easily remove the waste collection bin 111 from the floor cleaning assembly 12 and carry it separately to the sink to empty the wastewater or rinse the inner cavity. At the same time, the floor cleaning assembly 12 is stably supported by the base 13, ensuring that the base station as a whole remains upright after the waste collection bin 111 is removed, and is not prone to tipping over.

[0064] For example, the cleaning base station also includes a base 13. In the floor washing mode, the floor washing assembly 12 is detached from the base 13. In the dust collection mode, the floor washing assembly 12 is placed on the base 13 to ensure stable support for the dirt collection assembly 11 and the floor washing assembly 12, keeping them upright.

[0065] In some embodiments, continue to refer to Figure 1 and Figure 2 As shown, the sludge collection assembly 11 includes a sludge inlet pipe 114 and a sludge inlet valve 115, and the sludge inlet pipe 114 is connected to the outlet of the suction pipe 122.

[0066] In some embodiments, continue to refer to Figure 5 and Figure 6 As shown, in the floor cleaning mode, the inlet valve 115 connects the inlet pipe 114 to the collection chamber 1111.

[0067] In this embodiment, by setting independent inlet pipe 114 and inlet valve 115, the flow of water-containing airflow can be precisely controlled in the floor washing mode. In the dust collection mode, the inlet valve 115 is closed to prevent airflow from backflowing from the floor brush 121 side, ensuring that the airflow paths of the two modes do not interfere with each other.

[0068] For example, the outlet of the inlet pipe 114 is exposed inside the collection chamber 1111, and the inlet valve 115 is located at the outlet of the inlet pipe 114. When the collection assembly 11 is removed from the floor cleaning assembly 12, the inlet pipe 114 can be closed using the inlet valve 115 to prevent liquid in the collection chamber 1111 from flowing out through the inlet pipe 114 when the collection tank 111 is moved.

[0069] In some embodiments, continue to refer to Figure 1 As shown, the sewage inlet pipe 114 is fitted onto the sewage suction pipe 122, and the inner diameter of the sewage inlet pipe 114 is smaller than the inner diameter of the sewage collection box 111.

[0070] In this embodiment, the inner diameter of the inlet pipe 114 is smaller than the inner diameter of the collection box 111. When the water-containing airflow enters the coarse cavity from the thin pipe, the flow velocity drops sharply. The sewage and solid particles settle naturally under the action of gravity, thus achieving water-air separation. There is no need to set up a complicated cyclone separation structure.

[0071] For example, the inlet end of the inlet pipe 114 is sealed and connected to the outlet end of the suction pipe 122, while the outlet end of the inlet pipe 114 extends into the collection chamber 1111. The inlet valve 115 is located at the outlet end. In the floor washing mode, the inlet valve 115 is open, and the water-containing airflow enters the collection chamber 1111 via the suction pipe 122 and the inlet pipe 114. In the dust collection mode, the inlet valve 115 is closed to prevent the dust collection airflow from drawing in outside air from the floor brush 121 side, ensuring that the dust collection negative pressure is concentrated at the dust collection port 1112.

[0072] Furthermore, the inner diameter of the inlet pipe 114 is smaller than the inner cavity size of the sludge collection tank 111. When a high-speed water-laden airflow is injected from the slender inlet pipe 114 into the large sludge collection chamber 1111, the airflow velocity drops sharply. Heavier particles such as sewage and silt quickly settle to the bottom of the sludge collection chamber 1111 under the action of inertia and gravity, while the relatively clean air floats to the upper layer and is drawn away by the exhaust connector 113. This structure achieves efficient water-air separation by utilizing a simple abrupt change in pipe diameter, eliminating the need for complex baffles or cyclone cones inside the sludge collection chamber, thus reducing manufacturing costs and cleaning difficulty.

[0073] For example, the sludge collection box 111 adopts a cylindrical structure with a diameter of 90 mm.

[0074] In some embodiments, continue to refer to Figure 1 and Figure 4As shown, the dirt collection assembly 11 also includes a filter screen (not shown in the figure), which is disposed in the dust collection duct 112.

[0075] In this embodiment, the filter screen is installed inside the dust collection duct 112, which can finely filter the air returning in the dust collection mode, prevent fine dust from entering the negative pressure source (such as a negative pressure fan) and causing motor wear or secondary pollution, and extend the equipment life.

[0076] For example, in dust collection mode, the airflow after settling in the dust collection chamber 1111 may still contain a small amount of fine dust. To prevent this dust from entering the negative pressure source and causing motor wear or being discharged into the room and causing secondary pollution, a filter, such as a HEPA filter, is installed inside the dust collection duct 112 (e.g., near the air outlet). Furthermore, since the filter is located inside the dust collection duct 112, in floor washing mode, the water-containing airflow does not flow through the dust collection duct 112, so the filter can always remain dry, avoiding the problems of mold growth or increased resistance due to contact with moisture.

[0077] In some embodiments, continue to refer to Figure 1 As shown, the sludge collection assembly 11 includes a water baffle 117, which is located inside the sludge collection chamber 1111. The sludge inlet pipe 114 is located on one side of the water baffle 117, and the dust collection port 1112 and the exhaust connector 113 are located on the opposite side of the water baffle 117.

[0078] In this embodiment, the water-blocking component 117 divides the sewage collection chamber 1111 into a wet area and a dry area. When the cleaning base station 1 is tilted or lying flat, it can effectively prevent sewage from overflowing from the bottom of the sewage collection chamber 1111 from the dust collection port 1112 or the exhaust port 113, ensuring safety and preventing sewage backflow from damaging the cleaning equipment.

[0079] For example, considering that users may need to tilt the cleaning base station 1 when using the floor cleaning function (e.g., lying flat to clean the bottom of low furniture), a water-blocking component 117 (e.g., a baffle plate) is provided inside the dirt collection chamber 1111. The water-blocking component 117 extends inward from the inner wall of the dirt collection chamber 1111, dividing the lower space of the dirt collection chamber 1111 into a dirt inlet side and an exhaust side. The dirt inlet pipe 114 is located on one side of the water-blocking component 117 (e.g., the dirt inlet side), and the dust collection port 1112 and the exhaust connector 113 are located on the opposite side of the water-blocking component 117 (e.g., the exhaust side). When the cleaning base station 1 is tilted, the sewage at the bottom of the dirt collection chamber 1111 is blocked by the water-blocking component 117 and cannot pass over the water-blocking component 117 to reach the area where the dust collection port 1112 or the exhaust connector 113 is located, thereby effectively preventing sewage from overflowing and contaminating other components or flowing back into the cleaning equipment.

[0080] In some embodiments, continue to refer to Figure 3 As shown, the cleaning base station 1 also includes a liquid storage tank 123.

[0081] In this embodiment, in order to support the continuous operation of the floor cleaning mode, the cleaning base station 1 also includes a liquid storage tank (e.g., a clean water tank).

[0082] In some embodiments, continue to refer to Figure 1 As shown, the liquid storage tank 123 is connected to the floor scrubbing brush 121.

[0083] In this embodiment, the liquid storage tank 123 is directly integrated into the floor brush housing of the floor cleaning assembly 12, thereby shortening the water path length between the water storage tank 123 and the floor cleaning brush 121.

[0084] In a different embodiment not shown, the liquid storage tank 123 is connected to the sludge collection tank 111.

[0085] In this embodiment, the liquid storage tank 123 can also be connected to the side wall of the sludge collection tank 111, so as to facilitate cleaning together with the sludge collection tank 111, or to be removed from the floor cleaning assembly 12 together with the sludge collection assembly 11.

[0086] For example, the liquid storage tank 123 is integrated into the dirt collection component 11 or the floor washing component 12 to provide a clean water source for the floor washing mode. Users do not need to equip the water tank separately, so as to achieve self-sufficiency of the base station and improve the integration of the cleaning base station 1.

[0087] For example, the liquid storage tank 123 delivers clean water to the spray nozzle of the floor scrubbing brush 121 via a water pump and pipeline to wet the roller brush or rinse the squeegee. In addition, the floor scrubbing assembly 12 may also be equipped with a drying component 124 to dry the roller brush and pipeline with hot air after the floor scrubbing is completed, preventing bacterial growth.

[0088] According to a second aspect of this disclosure, a cleaning system is provided, comprising the aforementioned cleaning base station 1. This cleaning system possesses all the beneficial effects of the aforementioned cleaning base station 1, which will not be elaborated further herein.

[0089] Reference Figure 4 , Figure 5 and Figure 6 As shown, a cleaning system includes a cleaning device 2 (e.g., a handheld vacuum cleaner) and a cleaning base station 1.

[0090] In some embodiments, the cleaning device 2 includes a dust cup 21 and a cup valve 22, wherein the cup valve 22 is disposed in the dust cup 21.

[0091] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, cup valve 22 connects dust cup 21 to dust collection port 1112.

[0092] In this embodiment, in the dust collection mode, the cleaning device 2 stops at the cleaning base station 1, and the cup valve 22 is opened, so that the internal space of the dust cup 21 is connected to the dust collection port 1112 of the dirt collection box 111. At this time, the suction force generated by the negative pressure source can suck the dust temporarily stored in the dust cup 21 into the dirt collection chamber 1111 through the dust collection port 1112.

[0093] In some embodiments, continue to refer to Figure 5 As shown, in the floor washing mode, the cup valve 22 disconnects the connection between the dust cup 21 and the dust collection port 1112.

[0094] In this embodiment, in the floor washing mode, the cup valve 22 is closed, thereby cutting off the connection between the dust cup 21 and the dust collection port 1112, preventing the water-containing airflow in the dirt collection chamber 1111 from flowing back into the dust cup 21, avoiding the filter screen in the dust cup 21 from getting damp and clogged or the dust from hardening, while ensuring the independence and sealing of the floor washing air path.

[0095] For example, the bottom of the dust cup 21 of the cleaning device 2 is provided with a cup valve 22.

[0096] For example, in dust collection mode, the cleaning device 2 is docked at the cleaning base station 1, and the cup valve 22 is connected to the dust collection port 1112 of the dust collection box 111 and opens automatically or passively, connecting the internal space of the dust cup 21 with the dust collection chamber 1111. At this time, the negative pressure generated by the negative pressure fan draws the dust in the dust cup 21 into the dust collection chamber 1111. In floor washing mode or independent vacuuming mode, the cup valve 22 remains closed, ensuring that the dust cup 21 can normally hold the garbage or serve as part of the airflow channel without leakage.

[0097] In some embodiments, the cleaning system includes a negative pressure fan (not shown) and the cleaning device 2 includes a switching valve 24.

[0098] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, switching valve 24 connects dust collection duct 112 to negative pressure fan.

[0099] In some embodiments, continue to refer to Figure 5 As shown, in the floor cleaning mode, the switching valve 24 connects the dust cup 21 to the negative pressure fan, and the dirt collection chamber 1111 is connected to the upstream of the dust cup 21.

[0100] In this embodiment, the airflow path is switched by the switching valve 24 inside the cleaning device 2, so that the negative pressure fan (such as the negative pressure fan of the cleaning device 2 itself) can serve both vacuuming and dust collection and floor washing cycles in the cleaning base station 1, realizing multiple uses of one machine and simplifying the system control logic.

[0101] For example, a negative pressure fan can generate a negative pressure source, and this solution can be represented as a shared negative pressure fan by sharing a negative pressure source.

[0102] In some embodiments, continue to refer to Figure 6 As shown, the cleaning device 2 includes a handheld component 25, and a negative pressure fan is disposed on the handheld component 25.

[0103] In this embodiment, the negative pressure fan is installed inside the handheld component 25 of the cleaning device 2. The cleaning base station 1 does not need to have a built-in fan. The cleaning base station 1 only serves as a passive airway container, which reduces the size, weight and manufacturing cost of the cleaning base station 1, and facilitates miniaturization and storage.

[0104] Of course, the negative pressure fan can also be installed at the cleaning base station 1. Alternatively, the cleaning system can include multiple negative pressure fans, for example, negative pressure fans can be installed on both the cleaning base station 1 and the cleaning equipment 2 to meet different usage needs.

[0105] For example, the switching valve 24, dust cup 21, and negative pressure fan are all housed within the handheld assembly 25, forming a handheld vacuum cleaner.

[0106] In some embodiments, continue to refer to Figure 6 As shown, the handheld assembly 25 includes an air intake pipe 251.

[0107] In some embodiments, continue to refer to Figure 5 As shown, in the floor washing mode, the air intake pipe 251 connects the exhaust connector 113 to the dust cup 21.

[0108] In this embodiment, the handheld component 25 connects to the exhaust connector 113 via the air inlet pipe 251, thus enabling the dirt collection chamber 1111 and the dust cup 21 to communicate via the exhaust connector 113 and the air inlet pipe 251 during the floor cleaning mode. The complete air path in the floor cleaning mode is defined as follows: dirt collection chamber 1111, exhaust connector 113, air inlet pipe 251, dust cup 21, switching valve 24, and negative pressure fan. This air path design ensures that the water-containing airflow passes through multiple separation and filtration processes in the dirt collection chamber 1111 and dust cup 21 before entering the fan, protecting the negative pressure fan from moisture corrosion.

[0109] For example, such as Figure 6 As shown, the cleaning device 2 also includes a vacuuming assembly 26, which is detachably connected to an air intake pipe 251. The vacuuming assembly 26 includes a vacuuming brush 261 and a connecting pipe 262, which connects the vacuuming brush 261 to the air intake pipe 251 and is detachably connected to the air intake pipe 251.

[0110] For example, when the cleaning device 2 is vacuuming, or when the cleaning base station 1 is in dust collection mode, the vacuuming component 26 is connected to the air intake pipe 251 (i.e., the connecting pipe 262 is connected to the air intake pipe 251). When the cleaning base station 1 is in floor washing mode, the vacuuming component 26 (i.e., the connecting pipe 262) is detached from the air intake pipe 251.

[0111] For example, the handheld component 25 has an exhaust port 253 connected to the outlet of a negative pressure fan. In floor cleaning mode, the dirt collection chamber 1111, exhaust connector 113, air inlet pipe 251, dust cup 21, switching valve 24, negative pressure fan, and exhaust port 253 are arranged along the airflow direction. In dust collection mode, the vacuuming component 26 (i.e., vacuuming brush 261 and connecting pipe 262), air inlet pipe 251, dust cup 21, cup valve 22, dirt collection chamber 1111, dust collection duct 112, switching valve 24, negative pressure fan, and exhaust port 253 are arranged along the airflow direction.

[0112] For example, the cleaning system also includes a negative pressure fan installed inside the cleaning device 2 as a negative pressure source. The handheld component 25 of the cleaning device 2 is provided with a switching valve for switching the airflow path.

[0113] Specifically, such as Figure 4 As shown, in dust collection mode: the switching valve 24 is in the first state, connecting the dust collection duct 112 to the air inlet of the negative pressure fan. At this time, the airflow path is: dust collection brush 261, connecting pipe 262, air inlet pipe 251, dust cup 21, cup valve 22, dust collection port 1112, dirt collection chamber 1111, dust collection duct 112, switching valve 24, negative pressure fan, exhaust port 253. Dust is trapped in the dirt collection chamber 1111.

[0114] Specifically, such as Figure 5 As shown, in floor cleaning mode: the switching valve 24 is in the second state, connecting the dust cup 21 to the air inlet of the negative pressure fan, while the exhaust connector 113 extends and connects to the air inlet pipe 251 of the handheld assembly 25. At this time, the airflow path is: floor cleaning brush 121, suction pipe 122, inlet pipe 114, collection chamber 1111, exhaust connector 113, air inlet pipe 251, dust cup 21, switching valve 24, negative pressure fan, exhaust port 253. Wastewater in the water-containing airflow is trapped in the collection chamber 1111, and the relatively dry air is further separated by the dust cup 21 (e.g., internal cyclone separator) before entering the negative pressure fan.

[0115] With the above structure, the negative pressure fan built into the cleaning device 2 can provide dust suction power when used independently, and can also serve as a circulating power source for dust collection and floor washing when parked at the cleaning base station 1, realizing "one machine for three uses" and reducing the hardware redundancy of the entire cleaning system.

[0116] In some embodiments, continue to refer to Figure 4 and Figure 5 As shown, the cleaning device 2 has a first form and a second form.

[0117] In this embodiment, when the cleaning device 2 is docked at the cleaning base station 1, the cleaning device 2 can switch between the first mode and the second mode.

[0118] In some embodiments, such as Figure 4 As shown, in the first configuration, the handheld component 25 is connected to the vacuuming component 26, and the handheld component 25 connects the vacuuming component 26 to the dust cup 21.

[0119] In this embodiment, in the first state, the cleaning base station 1 can collect dust from the cleaning device 2, and the cleaning base station 1 is in dust collection mode.

[0120] In some embodiments, such as Figure 5 As shown, in the second configuration, the handheld component 25 is connected to the dirt collection component 11, and the handheld component 25 connects the dirt collection component 11 to the dust cup 21.

[0121] In this embodiment, in the second form, the cleaning device 2 and the cleaning base station 1 can be combined to form a washing device (e.g., a floor washing device) to perform a floor washing operation. At this time, the cleaning base station 1 is in the floor washing mode.

[0122] Of course, when the cleaning device 2 is detached from the cleaning base station 1, the cleaning device 2 can also switch to the first mode, at which time the cleaning device 2 can perform a vacuuming operation.

[0123] In some embodiments, such as Figure 4 As shown, in the first state, the switching valve 24 connects the dirt collection assembly 11 to the negative pressure source.

[0124] In this embodiment, in the first state (i.e., dust collection mode), after the airflow flows along the dust collection component 26, the handheld component 25, and the dust cup 21, the airflow in the dirt collection component 11 flows to the negative pressure source through the switching valve 24.

[0125] In some embodiments, such as Figure 5 As shown, in the second configuration, the switching valve 24 connects the dust cup 21 to the negative pressure source.

[0126] In this embodiment, in the second state (i.e., floor washing mode), the handheld component 25 is separated from the vacuuming component 26. After the airflow flows along the dirt collection component 11, the handheld component 25, and the dust cup 21, the airflow in the dust cup 21 flows to the negative pressure source through the switching valve 24.

[0127] Thus, in the first state, the switching valve 24 connects the dirt collection assembly 11 to the negative pressure source, which can extract the filtered gas in the dirt collection assembly 11. In the second state, the switching valve 24 connects the dust cup 21 to the negative pressure source, which can extract the filtered gas in the dust cup 21. Thus, by switching the state of the cleaning device 2 and the state of the switching valve 24, multiple cleaning functions are realized. There is no need to equip multiple cleaning devices separately, which simplifies the structure of the cleaning system and reduces the economic cost and space occupied by the cleaning system.

[0128] In some embodiments, continue to refer to Figure 4 As shown, in the first configuration, the cup valve 22 connects the dust cup 21 to the dirt collection assembly 11.

[0129] In some embodiments, continue to refer to Figure 5 As shown, in the second configuration, the cup valve 22 disconnects the connection between the dust cup 21 and the dirt collection assembly 11.

[0130] In this embodiment, the cup valve 22 connects the dust cup 21 and the dirt collection assembly 11 in the first state, allowing the dust temporarily stored in the dust cup 21 to be smoothly transferred to the dirt collection assembly 11. In the second state, the cup valve 22 isolates the dust cup 21 from the dirt collection assembly 11, preventing moisture from entering the dust cup 21 during floor washing mode and causing filter clogging or dust buildup, while also preventing residual debris in the dust cup 21 from accidentally falling into the dirt collection chamber 1111. The cup valve 22 enables automatic adaptation of the connection state between the dust cup 21 and the dirt collection assembly 11 in both modes.

[0131] For example, the cup valve 22 is used to control the connection and disconnection between the internal space of the dust cup 21 and the dirt collection assembly 11.

[0132] Specifically, in the first mode (dust collection mode), the cup valve 22 is open, and the dust cup 21 is connected to the dust collection port 1112 of the dirt collection assembly 11 through the cup valve 22. At this time, the negative pressure generated by the negative pressure fan can draw the dust temporarily stored in the dust cup 21 into the dirt collection chamber 1111 for collection through the cup valve 22. In the second mode (floor washing mode), the cup valve 22 is closed, and the connection between the dust cup 21 and the dirt collection assembly 11 is cut off. This not only prevents the water-containing airflow in the dirt collection chamber 1111 from flowing back into the dust cup 21 in the floor washing mode, wetting the filter screen or residual dust in the dust cup 21, but also prevents the dry waste remaining in the dust cup 21 from accidentally falling into the dirt collection chamber 1111 and contaminating the wastewater.

[0133] For example, the cup valve 22 may be a solenoid valve, a mechanically linked valve, or a check valve driven by negative pressure.

[0134] For example, such as Figure 4As shown, in the first configuration, the airflow flows along the suction assembly 26, handheld assembly 25, dust cup 21, dirt collection assembly 11, and switching valve 24 before flowing towards the negative pressure source. Figure 5 As shown, in the second state, the airflow flows along the dirt collection assembly 11, the handheld assembly 25, the dust cup 21, and the switching valve 24 before flowing towards the negative pressure source.

[0135] In some embodiments, continue to refer to Figure 5 As shown, in the second configuration, the handheld component 25 is connected to the exhaust connector 113, and the exhaust connector 113 connects the sludge collection chamber 1111 to the handheld component 25.

[0136] In this embodiment, in the second configuration, the handheld component 25 is connected to the sludge collection box 111 via the exhaust connector 113. The exhaust connector 113 serves as the air outlet of the sludge collection chamber 1111, guiding relatively clean air, after water-air separation or dust-air separation, to the handheld component 25, which then flows to the dust cup 21 for secondary filtration.

[0137] For example, the vent connector 113 is connected to the sludge collection tank 111, and the vent connector 113 is detachably connected to the handheld component 25. The detachable connection between the vent connector 113 and the handheld component 25 facilitates user operation; docking connects the components, and disassembling disconnects them.

[0138] In some embodiments, continue to refer to Figure 4 As shown, in the first configuration, the dust collection duct 112 connects the dirt collection chamber 1111 to the switching valve 24, and the handheld assembly 25 includes an air inlet pipe 251.

[0139] In this embodiment, in the first state, the dust collection duct 112 directly connects the dirt collection chamber 1111 to the switching valve 24, ensuring that after the dust-laden airflow settles in the dirt collection chamber 1111, the clean air flows orderly to the negative pressure source through the dust collection duct 112, thus preventing unseparated dust from short-circuiting and entering the fan.

[0140] In some embodiments, continue to refer to Figure 5 As shown, in the second configuration, the intake pipe 251 is connected to the exhaust connector 113, and the intake pipe 251 connects the exhaust connector 113 to the dust cup 21.

[0141] In this embodiment, in the second configuration, the air inlet pipe 251 is connected to the exhaust connector 113, connecting the dirt collection chamber 1111 to the dust cup 21. This allows the water-containing airflow to be separated in the dirt collection chamber 1111 and then enter the dust cup 21 for further filtration, improving the separation effect. The dust collection duct 112 and the air inlet pipe 251 each perform their respective functions without interfering with each other.

[0142] For example, the sludge collection assembly 11 includes a sludge collection tank 111 forming a sludge collection cavity 1111 and an exhaust connector 113 mounted on the side wall or top of the sludge collection tank 111. The exhaust connector 113 can be docked with the handheld assembly 25 in a second configuration.

[0143] Specifically, in the second configuration, the air inlet pipe 251 of the handheld component 25 is connected to the exhaust connector 113, so that the gas in the dust collection chamber 1111 can flow into the dust cup 21 through the exhaust connector 113 and the air inlet pipe 251.

[0144] Furthermore, the dust collection assembly 11 also includes a dust collection duct 112. One end of the dust collection duct 112 communicates with the upper space of the dust collection chamber 1111, and the other end extends to an interface for docking with the handheld assembly 25. In the first configuration, after the handheld assembly 25 docks with the dust collection assembly 11, the outlet of the dust collection duct 112 communicates with the switching valve 24 inside the handheld assembly 25, thereby connecting the dust collection chamber 1111 to the negative pressure source. At this time, the airflow settles through the dust collection chamber 1111 and is then orderly discharged through the dust collection duct 112, preventing unseparated dust from entering the negative pressure fan.

[0145] For example, in the second configuration, the connection between the dust collection duct 112 and the negative pressure source is blocked by the switching valve 24, preventing the fluid in the dust collection chamber 1111 from flowing into the dust collection duct 112. Meanwhile, the air inlet pipe 251 connects to the exhaust connector 113, connecting the dust collection chamber 1111 to the dust cup 21. At this time, after the airflow is separated in the dust collection chamber 1111, it enters the dust cup 21 through the exhaust connector 113 and the air inlet pipe 251 for secondary filtration.

[0146] For example, the exhaust connector 113 is detachably connected to the intake pipe 251.

[0147] In some embodiments, continue to refer to Figure 4 As shown, the dust cup 21 and the sludge collection box 111 are arranged along the axial direction of the dust cup 21.

[0148] In some embodiments, continue to refer to Figure 5 As shown, the dust collection duct 112 and the air inlet pipe 251 are arranged circumferentially around the axis of the dust cup 21.

[0149] In this embodiment, the dust cup 21 and the sludge collection box 111 are arranged axially, and the dust collection duct 112 and the air inlet pipe 251 are located on one side of the dust cup 21 (or the sludge collection box 111) in the radial direction. This layout allows the airflow to flow radially when entering and exiting the dust collection duct 112 and the air inlet pipe 251, increasing the airflow turning angle. This is beneficial for using inertial force to weaken incompletely separated particles that enter the downstream pipeline with the airflow, thereby improving the dust-air or water-air separation effect. At the same time, the axial arrangement makes the cleaning equipment 2 compact and stable in center of gravity when parked at the base station 1.

[0150] For example, in terms of spatial layout, the dust cup 21 and the sludge collection box 111 are arranged sequentially along the axial direction of the dust cup 21.

[0151] Specifically, when the cleaning device 2 is upright and parked at the cleaning base station 1, the sludge collection box 111 is located directly below the dust cup 21, and the two are coaxially arranged. The dust collection duct 112 and the air inlet pipe 251 are both located on one radial side of the dust cup 21 and the sludge collection box 111 (i.e., on the side along the axis of the dust cup 21). This layout requires the airflow to turn radially when entering the dust collection duct 112 or the air inlet pipe 251. The centrifugal force or inertial force generated during the turning process helps to throw the fine particles remaining in the airflow to the outside of the pipe or settle back into the sludge collection chamber 1111, thereby reducing the possibility of incompletely separated particles entering the downstream pipe (e.g., the switching valve 24 or the dust cup 21) with the airflow, and improving the separation efficiency of the system. At the same time, the dust collection duct 112 and the air inlet pipe 251 are arranged to extend along the axial direction of the dust cup 21, making full use of the height space of the cleaning base station 1, making the structure more compact.

[0152] For example, the dust collection duct 112 and the air inlet pipe 251 extend along the axial direction of the dust cup 21, so that the airflow direction in the dust collection duct 112 and the air inlet pipe 251 is along the axial direction of the dust cup 21, further reducing the flow of the unfiltered part in the dust collection chamber 1111 downstream.

[0153] For example, the dust collection duct 112 and the air inlet pipe 251 are located on opposite sides or on the same side of the axis of the dust cup 21.

[0154] In some embodiments, in conjunction with reference Figure 6 , Figure 7 and Figure 8 As shown, the switching valve 24 has an air inlet 241 and a vent 242.

[0155] In some embodiments, in the first configuration, the air inlet 241 connects the dust collection duct 112 to the negative pressure source.

[0156] In some embodiments, in the second configuration, the vent 242 connects the dust cup 21 to the negative pressure source.

[0157] In some embodiments, the axis of the air inlet 241 extends radially along the dust cup 21, and the axis of the vent 242 extends axially along the dust cup 21.

[0158] In this embodiment, the air inlet 241 of the switching valve 24 extends radially along the dust cup 21 and naturally connects with the radially located dust collection duct 112. The vent 242 extends axially along the dust cup 21 and naturally connects with the axial air outlet of the dust cup 21. This differentiated directional design meets the installation requirements when the outlet of the dust cup 21 and the outlet of the dust collection duct 112 are in different spatial positions, allowing the switching valve 24 to be compactly arranged upstream of the negative pressure fan inlet, reducing pipe bends and flow resistance.

[0159] In this embodiment, in the first configuration, the air inlet 241 is connected to the outlet of the dust collection duct 112, connecting the dust collection duct 112 to the negative pressure source. Since the dust collection duct 112 is located on the radial side of the dust collection box 111, the air inlet 241, extending radially, can naturally connect with the dust collection duct 112, reducing airflow deflection.

[0160] In this embodiment, in the second configuration, the vent 242 connects to the outlet of the dust cup 21, linking the dust cup 21 to the negative pressure source. Since the dust cup 21 employs a cyclone separation structure, its outlet is located at the axial center of the dust cup 21. The vent 242, extending axially, can directly connect to the outlet of the dust cup 21, conforming to the airflow direction of cyclone separation. The differentiated directional design of the inlet 241 and the vent 242 allows a single switching valve 24 to simultaneously adapt to both the radial dust collection duct 112 and the axial outlet of the dust cup 21, resulting in a compact structure and convenient installation.

[0161] In some embodiments, continue to refer to Figure 7 and Figure 8 As shown, the switching valve 24 includes an intake valve 243 and a ventilation valve 244, and the switching valve 24 has a first state and a second state.

[0162] In some embodiments, such as Figure 7 As shown, in the first state, the intake valve 243 opens the intake port 241, and the ventilation valve 244 closes the ventilation port 242.

[0163] In some embodiments, such as Figure 8 As shown, in the second state, the intake valve 243 closes the intake port 241, and the ventilation valve 244 opens the ventilation port 242.

[0164] In this embodiment, through the coordinated control of the air intake valve 243 and the ventilation valve 244, the switching valve 24 always keeps only one of the air intake port 241 and the ventilation port 242 in the open state, while the other is in the closed state. This interlocking design ensures stable switching of the air path, avoids crosstalk between the airflow paths in integrated mode and floor washing mode, and improves the reliability of the system operation.

[0165] For example, the intake valve 243 and the ventilation valve 244 can be interlocked through mechanical linkage or electronic control to ensure that only one air port is open at any given time.

[0166] In some embodiments, continue to refer to Figure 7 and Figure 8 As shown, the switching valve 24 includes a valve body 245, which has a bottom wall 2451 and a side wall 2452. The side wall 2452 is connected to the periphery of the bottom wall 2451. A vent 242 is disposed on the bottom wall 2451, an air inlet 241 is disposed on the side wall 2452, a ventilation door 244 is rotatably disposed on the bottom wall 2451, and an air inlet door 243 is connected to the side wall 2452.

[0167] In this embodiment, the air inlet 241 is disposed on the side wall 2452 of the valve body, and the air inlet valve 243 is pivotally connected to the side wall 2452. The vent 242 is disposed on the bottom wall 2451 of the valve body, and the vent valve 244 is rotatably disposed on the bottom wall 2451 (i.e., the vent valve 244 can rotate relative to the bottom wall 2451). This structure is compact, and the switching between the two air paths can be achieved using simple rotational movement. It is convenient to achieve linkage control through a single drive motor (or linkage control through two drive motors respectively), reducing manufacturing costs and control complexity.

[0168] For example, the valve body 245 has a bottom wall 2451 and a side wall 2452 extending upward from the periphery of the bottom wall 2451. A vent 242 is formed on the bottom wall 2451, and an air inlet 241 is formed on the side wall 2452. A ventilation door 244 is mounted on the bottom wall 2451 via a drive motor (e.g., after the drive motor is mounted on the bottom wall 2451, the ventilation door 244 is connected to the output of the drive motor), and is rotatable about an axis parallel to the axial direction of the dust cup 21 to open or close the vent 242. An air inlet door 243 is hinged to the side wall 2452 via a pivot and is rotatable about an axis parallel to the axial direction of the dust cup 21 to open or close the air inlet.

[0169] For example, multiple vents 242 can be provided on the bottom wall 2451. The multiple vents 242 can be evenly distributed around the axis of the dust cup 21 on the bottom wall 2451 to increase the ventilation area, reduce airflow resistance, and achieve uniform airflow between the air outlet of the dust cup 21 and the air inlet of the negative pressure fan.

[0170] For example, two drive motors drive the ventilation door 242 and the air intake door 243 to rotate respectively.

[0171] In some embodiments, continue to refer to Figure 7 and Figure 8As shown, a negative pressure chamber 246 is formed by the negative pressure fan (not shown in the figure) and the valve body 245. The air inlet of the negative pressure fan is exposed in the negative pressure chamber 246. In the first state, the air inlet 241 is connected to the negative pressure chamber 246. In the second state, the vent 242 is connected to the negative pressure chamber 246.

[0172] In this embodiment, the negative pressure fan and valve body 245 together form a negative pressure chamber 246, with the air inlet of the negative pressure fan exposed within this chamber 246. Whether the air inlet 241 or the vent 242 is open, it communicates with the negative pressure fan's air inlet through the negative pressure chamber 246. The negative pressure chamber 246 serves to gather and buffer airflow, making the air intake of the negative pressure fan more uniform and stable, while also simplifying the sealing structure between the switching valve 24 and the negative pressure fan.

[0173] For example, the negative pressure fan and valve body 245 together form a closed negative pressure chamber 246. The air inlet of the negative pressure fan is exposed inside this negative pressure chamber 246. Regardless of whether the switching valve 24 is in the first state (i.e., the air inlet 241 is open) or the second state (i.e., the vent 242 is open), the airflow first enters the negative pressure chamber 246 and is then drawn in by the negative pressure fan. The negative pressure chamber 246 serves to gather and buffer the airflow, making the air intake of the negative pressure fan more uniform, reducing airflow pulsation noise, and also simplifying the sealing structure design between the switching valve 24 and the air inlet of the negative pressure fan.

[0174] For example, such as Figure 6 As shown, the handheld assembly 25 includes a fan housing 252, which has a receiving cavity and an exhaust port 253. The exhaust port of the negative pressure fan is exposed in the receiving cavity, and the exhaust port 253 is connected to the receiving cavity, so that the airflow discharged by the negative pressure fan can be discharged to the outside through the receiving cavity and the exhaust port 253.

[0175] In some embodiments, the cleaning system includes a negative pressure fan (not shown) that forms a negative pressure source.

[0176] In some embodiments, the negative pressure fan, switching valve 24, and dust cup 21 are arranged sequentially along the axial direction of the dust cup 21.

[0177] In this embodiment, the negative pressure fan, switching valve 24, and dust cup 21 are arranged sequentially along the axial direction. The switching valve 24 is located between the negative pressure fan and the dust cup 21, facilitating direct axial connection between the vent 242 and the dust cup 21 and the negative pressure fan. The sludge collection box 111 is located on the side of the dust cup 21 away from the switching valve 24. The three components are arranged coaxially, allowing the cleaning device 2 to stand upright when placed on the cleaning base station 1, occupying minimal horizontal space and facilitating home storage.

[0178] Specifically, the negative pressure fan is located at the upper end of the handheld assembly 25, the switching valve 24 is adjacent to the air inlet of the negative pressure fan below, and the dust cup 21 is located below the switching valve 24. This axially stacked layout has the following advantages: First, the switching valve 24 is located between the negative pressure fan and the dust cup 21, which facilitates the vent 242 to directly connect the air outlet of the dust cup 21 with the air inlet of the negative pressure fan along the axial direction, resulting in a short and straight airflow path and low flow resistance; Second, the sludge collection box 111 is located on the side of the dust cup 21 away from the switching valve 24 along the axial direction (i.e., below the dust cup 21). When the cleaning device 2 is placed on the cleaning base station 1, the whole machine is in an upright posture, with a low center of gravity, good stability, and less horizontal space occupation, making it convenient for home storage.

[0179] For example, a negative pressure fan can create a negative pressure source within the negative pressure chamber 246.

[0180] In some embodiments, continue to refer to Figure 4 As shown, in the first configuration, the connecting pipe 262 connects the air intake pipe 251 to the vacuum brush 261 and connects the air intake pipe 251 to the vacuum brush 261.

[0181] In this embodiment, in the first mode (i.e., dust collection mode), the connecting pipe 262 connects the air inlet pipe 251 to the vacuum brush 261. External air can enter the dust cup 21 through the vacuum brush 261, connecting pipe 262, and air inlet pipe 251, forming a complete dust collection airflow circuit. At this time, the cup valve 22 opens, and the airflow can carry the debris in the dust cup 21 into the dirt collection chamber 1111, completing the dust collection operation. Therefore, the dust collection operation can be performed without detaching the connecting pipe 262 from the air inlet pipe 251. That is, the cleaning device 2, after vacuuming, only needs to be placed on the cleaning base station 1 to perform the dust collection operation, and only needs to ensure that the dust cup 21 is connected to the dust collection port 1112. The detachable design of the connecting pipe 262 and the air inlet pipe 251 allows the cleaning device 2 to flexibly switch between the first mode (i.e., dust collection mode) and the independent vacuuming mode.

[0182] For example, in the first configuration, the handheld component 25 is connected to the vacuuming component 26, and the connecting pipe 262 connects the air intake pipe 251 of the handheld component 25 to the vacuuming brush 261. At this time, outside air can enter through the suction port of the vacuuming brush 261, and flow sequentially through the connecting pipe 262 and the air intake pipe 251 into the dust cup 21. In the dust collection mode, the cup valve 22 is opened, and the airflow carrying the dust in the dust cup 21 continues to flow to the dirt collection component 11, forming a complete dust collection circuit. The connecting pipe 262 and the air intake pipe 251 are connected by a detachable connection (such as a snap-fit, thread, or quick-connect fitting), allowing the user to easily detach the handheld component 25 from the vacuuming component 26 and connect it to the dirt collection component 11, thus achieving configuration switching. The connecting pipe 262 is located on the radial side of the dirt collection box 111, sharing the radial space of the cleaning base station 1 with the dust collection duct 112 and the air intake pipe 251, resulting in a reasonable layout.

[0183] In some embodiments, continue to refer to Figure 5 As shown, in the second configuration, the floor scrubbing brush 121, the suction pipe 122, and the dirt collection assembly 11 are connected along the airflow direction.

[0184] In this embodiment, the cleaning system can perform a self-cleaning function in the second state. The water-containing airflow enters the dirt collection component 11 from the floor brush 121 through the suction pipe 122 for water-air separation, which further expands the functional boundaries of the cleaning system and realizes the three-in-one function of vacuuming, dust collection and floor cleaning.

[0185] For example, in the second configuration, the cleaning device 2 connects to the cleaning base station 1. The water-containing airflow in the floor scrubbing brush 121 is drawn into the collection chamber 1111 of the dirt collection component 11 via the suction pipe 122 for water-air separation. The airflow path is: floor scrubbing brush 121, suction pipe 122, collection chamber 1111, exhaust connector 113, air inlet pipe 251, dust cup 21, switching valve 24 (at which time the vent 242 is open), negative pressure chamber 246, negative pressure fan, and exhaust vent 253. Wastewater and solid particles are trapped in the collection chamber 1111, while clean air is discharged after multiple separations. Thus, the cleaning system achieves a self-cleaning function in the second configuration, which, together with the dust collection function of the first configuration and the independent suction function, constitutes a three-in-one full-scene cleaning solution of "vacuuming-dust collection-floor scrubbing".

[0186] In some embodiments, continue to refer to Figure 4 , Figure 5 and Figure 6 As shown, the dirt collection assembly 11 has a dirt collection chamber 1111, the dust cup 21 has a dust collection chamber 211, and the cleaning system includes a switching valve 24 configured to switch the cleaning station 1 between a dust collection mode and a floor washing mode.

[0187] In this embodiment, the user only needs to connect the cleaning device 2 to the cleaning base station 1 and select the corresponding mode (such as dust collection mode or floor washing mode) through the centralized control of the switching valve 24, and the system can automatically complete the air path switching. There is no need for the user to manually plug or unplug different pipes or replace accessories with different functions (such as replacing the dust collection box or wastewater tank separately), making the operation intuitive and convenient.

[0188] In some embodiments, the cleaning system has an air intake passage 2511 and a dust collection passage 1121.

[0189] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, the air intake path 2511, dust collection chamber 211, dirt collection chamber 1111, and dust collection path 1121 are connected along the airflow direction.

[0190] In some embodiments, continue to refer to Figure 5As shown, in the floor washing mode, the dirt collection chamber 1111, the air intake passage 2511, and the dust collection chamber 211 are connected along the airflow direction.

[0191] In this embodiment, by reusing the sludge collection chamber 1111 as both the dust-air separation chamber and the water-air separation chamber, the cleaning base station 1 does not need to be equipped with multiple independent sludge collection containers. One set of sludge collection chamber 1111 can support both dust collection and floor cleaning maintenance modes. This reduces the number of components and the overall size of the cleaning base station 1, thereby reducing manufacturing costs and the space occupied in the user's home.

[0192] Therefore, the cleaning base station 1 can use the dirt collection chamber 1111 for filtration in both dust collection mode and floor washing mode, without the need to set up multiple independent dirt collection containers, thus reducing the economic cost and space occupation of the cleaning system.

[0193] In this embodiment, in dust collection mode, the air intake path 2511 is used to introduce external dust-laden airflow into the dust collection chamber 1111. In floor washing mode, the air intake path 2511 is used to introduce relatively clean air separated from the dirt collection chamber 1111 into the dust collection chamber 211. This reuse design reduces the number of pipes inside the cleaning base station 1 and the cleaning equipment 2, making the air path structure more compact, reducing airflow resistance, and improving energy efficiency.

[0194] In this embodiment, during the floor washing mode, the sludge collection chamber 1111 acts as an upstream primary water-air separator (e.g., by using the principle of chamber expansion and deceleration to allow sewage to settle first), and then the airflow enters the dust collection chamber 211 (e.g., a cyclone separator) for secondary fine separation. This cascaded design of "coarse separation first, then fine separation" effectively reduces the water vapor content entering the dust collection chamber 211, prevents the filter screen inside the dust collection chamber 211 from becoming clogged or breeding bacteria due to moisture, extends the service life of the filter components, and ensures stable dust collection performance.

[0195] For example, the sludge collection chamber 1111 can be used to contain dry dust in dust collection mode, or to contain sewage and solid particles in floor washing mode.

[0196] For example, the dust collection chamber 211 can be formed inside the dust cup 21. The dust cup 21 may also be provided with structures such as a cyclone separator cone and a filter screen to separate the sucked-in dust from the air during the dust collection operation and temporarily store the dust in the dust collection chamber 211.

[0197] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, switching valve 24 connects dust collection air path 1121 to negative pressure fan.

[0198] In some embodiments, continue to refer to Figure 5 As shown, in the floor washing mode, the switching valve 24 connects the dust collection chamber 211 to the negative pressure fan.

[0199] In this embodiment, by placing the negative pressure fan downstream of both the dust collection circulation air path and the floor washing circulation air path, the same negative pressure source can simultaneously serve both the dust collection mode and the floor washing mode. The switching valve 24 connects the dust collection air path 1121 or the dust collection chamber 211 to the negative pressure fan in both modes, ensuring that the negative pressure is precisely applied to the target air path. This avoids redundant design by requiring multiple fans for different modes, simplifies the system structure, and reduces manufacturing costs and energy consumption.

[0200] For example, the cleaning system also includes a negative pressure fan for generating a suction airflow. The negative pressure fan is located inside the handheld assembly 25 of the cleaning device 2 and serves as a vacuum source for the entire cleaning system.

[0201] For example, in the dust collection mode, the switching valve 24 is in the first state, connecting the outlet of the dust collection air path 1121 with the air inlet of the negative pressure fan. At this time, the suction force generated by the negative pressure fan acts sequentially on the dust collection air path 1121, the dirt collection chamber 1111, the dust collection chamber 211, and the air inlet air path 2511, driving the external dust-laden airflow to flow along this path to complete the dust collection operation.

[0202] For example, in the floor cleaning mode, the switching valve 24 is in the second state, connecting the air outlet of the dust collection chamber 211 with the air inlet of the negative pressure fan. At this time, the suction force of the negative pressure fan acts sequentially on the dust collection chamber 211, the air inlet 2511 and the dirt collection chamber 1111, driving the water-containing airflow generated by floor cleaning to flow along this path, completing the self-cleaning operation of floor cleaning.

[0203] With the above structure, the same negative pressure fan is shared by both the dust collection mode and the floor washing mode, eliminating the need for a separate fan for the floor washing function. This effectively simplifies the power structure of the cleaning system and reduces the overall weight and manufacturing cost. Furthermore, the negative pressure fan is located downstream of the entire circulating air path, ensuring that the dirt collection chamber 1111 and the dust collection chamber 211 are always under negative pressure. This helps prevent unfiltered airflow from leaking outwards, guaranteeing the cleanliness of the air used.

[0204] In some embodiments, such as Figure 6 As shown, switching valve 24 and negative pressure fan (not shown in the figure) are installed in cleaning equipment 2.

[0205] In this embodiment, by integrating the switching valve 24 and the negative pressure fan within the handheld assembly 25 of the cleaning device 2, an integrated design of the negative pressure source and the switching mechanism is achieved. The switching valve has independent air inlets 241 and vents 242, which are responsible for the airflow connection in dust collection mode and floor cleaning mode, respectively. This design allows the cleaning device 2 to be used independently without the cleaning base station 1, with the switching valve 24 directly connecting the dust collection chamber 211 to the negative pressure fan via the vent 242, enabling conventional dust collection functions and further expanding the application scenarios of the cleaning system, achieving "one machine, three uses".

[0206] In some embodiments, continue to refer to Figure 1 and Figure 2 As shown, the sludge collection assembly 11 has a sludge inlet air passage 1141.

[0207] In some embodiments, continue to refer to Figure 5 As shown, in the floor cleaning mode, the inlet valve 115 connects the inlet air passage 1141 to the collection chamber 1111, and the inlet air passage 1141 is located upstream of the collection chamber 1111.

[0208] In this embodiment, during the floor washing mode, the inlet valve 115 is opened, allowing the water-containing airflow to smoothly enter the collection chamber 1111 through the inlet air passage 1141 for water-air separation.

[0209] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, the inlet valve 115 disconnects the connection between the inlet air passage 1141 and the dust collection chamber 1111.

[0210] In this embodiment, during dust collection mode, the inlet valve 115 is closed, blocking the connection between the dust collection chamber 1111 and the inlet air path 1141, preventing the dust collection airflow from leaking from the inlet air path 1141, ensuring that the dust collection negative pressure is concentrated at the dust collection port 1112, and improving dust collection efficiency. The setting of the inlet valve 115 realizes the automatic isolation of the inlet path in the two modes.

[0211] For example, the sludge collection assembly 11 also has a sludge inlet passage 1141 inside, and is provided with a sludge inlet valve 115 for controlling the opening and closing of the sludge inlet passage 1141. The outlet end of the sludge inlet passage 1141 extends into the sludge collection chamber 211. The sludge inlet valve 115 is located at the outlet of the sludge inlet passage 1141, and can specifically be a flap valve driven by electromagnetic or mechanical means.

[0212] For example, in the floor cleaning mode, the inlet valve 115 is opened, connecting the inlet air passage 1141 to the collection chamber 1111. At this time, the water-containing airflow from the floor cleaning assembly 12 can smoothly enter the collection chamber 1111 via the inlet air passage 1141 for water-air separation. The inlet air passage 1141 is located upstream of the collection chamber 1111, ensuring that the water-containing airflow is guided in an orderly manner before entering the collection chamber 1111, thus preventing turbulence within the collection chamber 111 that could affect the separation effect.

[0213] For example, in dust collection mode, the inlet valve 115 is closed, isolating the connection between the inlet air passage 1141 and the dust collection chamber 1111. This design prevents the dust-laden airflow in the dust collection chamber 1111 from leaking back through the inlet air passage 1141 to the floor scrubbing assembly 12 side in dust collection mode, ensuring that the negative pressure of dust collection is concentrated on the dust collection port 1112, thereby ensuring the efficiency of waste transfer in the dust cup 21. The automatic switching of the inlet valve 115 reduces manual operation by the user and improves ease of use.

[0214] In some embodiments, such as Figure 1 As shown, the floor cleaning assembly 12 includes a suction air passage 1221.

[0215] In some embodiments, continue to refer to Figure 5 As shown, in the floor cleaning mode, the suction air passage 1221 is connected to the upstream of the inlet air passage 1141.

[0216] In this embodiment, by setting up the floor cleaning component 12 and its internal suction air passage 1221, in the floor cleaning mode, the suction air passage 1221 is located upstream of the inlet air passage 1141, which can orderly guide the water-containing airflow generated at the floor cleaning brush into the inlet air passage 1141. The suction air passage 1221 is connected to the floor cleaning port of the floor cleaning brush 121, which can effectively collect the sewage and particles generated during the roller brush cleaning process, ensuring the smooth operation of the floor cleaning self-cleaning.

[0217] For example, the floor scrubbing assembly 12 is disposed at the bottom of the cleaning base station 1 and is used to clean and maintain the floor brush roller. The floor scrubbing assembly 12 has a suction air passage 1221 inside. The inlet of the suction air passage 1221 is connected to the cleaning tank of the floor scrubbing brush 121, and the outlet extends to the interface that connects with the inlet air passage 1141 of the dirt collection assembly 11.

[0218] For example, in the floor cleaning mode, the floor brush is placed in the cleaning tank of the floor cleaning brush 121, and the suction air passage 1221 is connected to the inlet air passage 1141. At this time, the suction air passage 1221 is located upstream of the inlet air passage 1141, and the two together form a complete channel for transporting water-containing airflow from the floor cleaning brush 121 to the collection chamber 1111. When the negative pressure fan is started, the water-containing mixed airflow generated in the cleaning tank is first drawn into the suction air passage 1221, then flows through the inlet air passage 1141, and finally enters the collection chamber 1111 for water-air separation.

[0219] For example, the diameter of the suction air passage 1221 can be designed to gradually narrow to improve airflow speed and carrying capacity, ensuring that sewage and particles can be effectively transported to the collection chamber 1111, avoiding accumulation and blockage in the pipe. The floor washing assembly 12 and the collection assembly 11 adopt a detachable sealed connection structure to ensure the airtightness of the air passage connection.

[0220] In some embodiments, such as Figure 5 As shown, an air intake passage 2511 is formed on the handheld assembly 25, and a dirt collection assembly 11 has an exhaust passage 1131.

[0221] In some embodiments, continue to refer to Figure 5 As shown, in the floor cleaning mode, the exhaust air passage 1131 connects the dirt collection chamber 1111 with the air intake air passage 2511.

[0222] In this embodiment, by setting the air intake duct 2511 inside the handheld component 25 and setting the exhaust duct 1131 on the dirt collection component 11, in the floor cleaning mode, the dirt collection chamber 1111 is connected to the air intake duct 2511 of the handheld component 25 through the exhaust duct 1131. Compared with the dirt collection box 111 being directly connected to the air intake pipe 251, the addition of the exhaust duct 1131 (such as through the exhaust connector 113) facilitates the rapid docking and sealing between the cleaning device 2 and the cleaning base station 1 in the floor cleaning mode, reduces the docking accuracy requirements, and improves the assembly convenience and airtightness.

[0223] For example, one end of the air intake duct 2511 is connected to the air inlet of the dust cup 21, and the other end extends to the front end interface of the handheld assembly 25. The exhaust duct 1131 is formed inside the exhaust connector 113 on the side wall of the sludge collection box 111. The exhaust connector 113 is rotatably or retractably mounted on the sludge collection box 111, and its internal channel is the exhaust duct 1131.

[0224] For example, in the floor cleaning mode, the user connects the handheld component 25 to the dirt collection component 11. Specifically, the interface at the front end of the handheld component 25 connects to the exhaust connector 113, connecting the air intake path 2511 and the exhaust path 1131. At this time, the airflow in the dirt collection chamber 1111 can sequentially enter the dust collection chamber 211 of the dust cup 21 through the exhaust path 1131 and the air intake path 2511. Compared to directly connecting the air outlet of the dirt collection box 111 to the air intake pipe of the handheld component 25, by adding an independent exhaust connector 113 and exhaust path 2511, a flexible transition connection section can be provided between the dirt collection box 111 and the handheld component 25. This design not only reduces the mechanical precision requirements during connection, making it easier for users to complete the assembly, but also facilitates the integration of functional components such as sealing rings and one-way valves in the exhaust connector 113, improving the airtightness and reliability of the connection.

[0225] For example, in dust collection mode, the exhaust connector 113 can be housed within the outer contour of the dust collection box 111 to avoid interference with the handheld component 25 or other components.

[0226] In some embodiments, such as Figure 4 As shown, the vacuuming assembly 26 has a connecting air passage 2621.

[0227] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, the air intake duct 2511 connects the dust collection chamber 211 with the connecting air duct 2621.

[0228] In this embodiment, by setting up a connecting air passage 2621, in dust collection mode, the air intake passage 2511 connects the dust collection chamber 211 to the connecting air passage 2621. The connecting air passage 2621 is connected downstream of the vacuuming brush 261, so that after the cleaning device 2 performs a vacuuming operation, it can be directly placed on the cleaning base station 1 for dust collection without disassembling the connecting pipe 262. The user only needs to ensure that the dust cup 21 is connected to the dust collection port 1112, and the system can automatically complete the connection of the dust collection air passage, which is convenient and reduces the user's operation steps.

[0229] For example, the vacuuming assembly 26 is detachably attached to the front end of the handheld assembly 25 for sucking up external debris when vacuuming independently.

[0230] For example, in dust collection mode, the vacuuming assembly 26 remains connected to the handheld assembly 25, and the connecting air passage 2621 is connected to the air intake passage 2511 of the handheld assembly 25. At this time, the air intake passage 2511 connects the dust collection chamber 211 to the connecting air passage 2621, which in turn connects the air intake passage 2511 to the suction port of the vacuuming brush 261. External air can enter through the suction port of the vacuuming brush 261, flowing sequentially through the connecting air passage 2621 and the air intake passage 2511 before entering the dust collection chamber 211. The advantage of this design is that after completing daily vacuuming, the user does not need to remove the vacuuming assembly 26 from the handheld assembly 25; the entire cleaning device 2 can be directly placed on the cleaning base station 1 for dust collection. The user only needs to ensure that the cup valve 22 at the bottom of the dust cup 21 is connected to the dust collection port 1112 of the dust collection box 111, and the internal airflow of the system automatically forms a complete dust collection circuit. This simplifies the user's operating process, reduces interface wear caused by frequent plugging and unplugging of pipes, and improves the product's ease of use and durability. The connecting air duct 2621 is located on the radial side of the sludge collection box 111 and is arranged in parallel with the dust collection air duct 1121, making full use of the internal space of the cleaning base station 1.

[0231] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, cup valve 22 connects dust collection chamber 211 with dirt collection chamber 1111.

[0232] In some embodiments, continue to refer to Figure 5 As shown, in the floor washing mode, the cup valve 22 disconnects the connection between the dust collection chamber 211 and the dirt collection chamber 1111.

[0233] In this embodiment, by setting a cup valve 22, in dust collection mode, the cup valve 22 opens, connecting the dust collection chamber 211 and the dirt collection chamber 1111, allowing the waste in the dust collection chamber 211 to be smoothly transferred to the dirt collection chamber 1111. In floor washing mode, the cup valve 22 closes, blocking the airflow in the dirt collection chamber 211 from directly flowing into the dust collection chamber 1111, forcing the water-containing airflow into the dust collection chamber 211 through the air inlet pipe 251, achieving cascade separation. The cup valve 22 ensures the unobstructed waste passage during dust collection and prevents the direct impact of moisture on the filter screen inside the dust collection chamber 211 during floor washing.

[0234] For example, the cleaning device 2 also includes a cup valve 22 disposed at the bottom of the dust cup 21. The cup valve 22 is used to control the opening and closing of the dust collection chamber 211 and the dirt collection chamber 1111.

[0235] For example, in dust collection mode, cup valve 22 opens, connecting dust collection chamber 211 with dirt collection chamber 1111. At this time, the airflow entering dust collection chamber 211 through air intake duct 2511 can lift the dust temporarily stored in dust collection chamber 211 and carry it through cup valve 22 into dirt collection chamber 1111, completing the transfer of waste from dust cup 21 to dirt collection chamber 111. The opening of cup valve 22 can be active (e.g., driven by a motor).

[0236] For example, in the floor washing mode, the cup valve 22 is closed, cutting off the direct connection between the dust collection chamber 211 and the dirt collection chamber 1111. At this time, the water-laden airflow from the dirt collection chamber 1111 cannot directly enter the dust collection chamber 211 through the cup valve 22, but instead enters the upper air inlet of the dust collection chamber 211 through the exhaust air passage 1131 and the intake air passage 2511. This design ensures that the water-laden airflow undergoes sufficient path guidance before entering the dust collection chamber 211 and can enter the cyclone separation structure within the dust collection chamber 211 in the correct direction, achieving effective secondary separation. Simultaneously, the closure of the cup valve 22 also prevents wastewater from the dirt collection chamber 1111 from accidentally splashing into the dust collection chamber 211 during the floor washing mode, protecting the dry environment within the dust collection chamber 211.

[0237] In some embodiments, in the dust collection mode, the air inlet 241 connects the dust collection air path 1121 to the air inlet of the negative pressure fan.

[0238] In this embodiment, during dust collection mode, the air inlet 241 of the switching valve 24 is opened and the vent 242 is closed, connecting the outlet of the dust collection air path 1121 with the air inlet of the negative pressure fan. At this time, the negative pressure fan draws airflow from the dust collection air path 1121 through the air inlet 241.

[0239] In some embodiments, during the floor cleaning mode, the vent 242 connects the dust collection chamber 211 to the air inlet of the negative pressure fan.

[0240] In this embodiment, during the floor cleaning mode, the vent 242 of the switching valve 24 is opened and the air inlet 241 is closed, connecting the air outlet of the dust collection chamber 211 with the air inlet of the negative pressure fan. At this time, the negative pressure fan draws airflow from the dust collection chamber 211 through the vent 242.

[0241] For example, the switching valve 24 is located inside the cleaning device 2, such as near the air inlet of the negative pressure fan, making the airflow path more compact and reducing pipe length and flow resistance. Simultaneously, when the cleaning device 2 operates independently of the cleaning base station 1, the switching valve 24 can switch to the open state of the vent 242, directly connecting the dust collection chamber 211 to the negative pressure fan, enabling regular dust collection. This integrated design allows a single negative pressure fan and switching valve 24 to simultaneously serve three work scenarios: independent dust collection, base station dust collection, and base station floor cleaning, achieving a high degree of functional reuse.

[0242] In some embodiments, a sludge collection chamber 1111 is formed within a sludge collection box 111.

[0243] In some embodiments, in conjunction with reference Figure 4 As shown, in dust collection mode, dust collection port 1112 is connected to the upstream of dirt collection chamber 1111.

[0244] In this embodiment, by providing a dust collection port 1112 on the sludge collection box 111 and connecting it to the upstream of the sludge collection chamber 1111 in dust collection mode, the waste in the dust cup 21 can fall directly into the sludge collection chamber 1111 through the dust collection port 1112, simplifying the waste transfer path. Combined with the cup valve 22 on the dust cup 21, the waste can be transferred by gravity and airflow, resulting in a simple and reliable structure. Simultaneously, the dust collection port 1112 can be located at the top of the sludge collection box 111, facilitating the smooth discharge of waste when the sludge collection box 111 is removed and emptied.

[0245] For example, the dirt collection assembly 11 includes a dirt collection box 111, the interior of which is hollow to form a dirt collection chamber 1111. A dust collection port 1112 is provided at the top of the dirt collection box 111, which is used to connect with the cup valve 22 of the cleaning device 2 in dust collection mode. In dust collection mode, the dust collection port 1112 is located upstream of the dirt collection chamber 1111, meaning that airflow and debris first pass through the dust collection port 1112 before entering the dirt collection chamber 1111.

[0246] Specifically, the dust-laden airflow within the dust cup 21 flows downwards under negative pressure through the cup valve 22 and directly enters the dirt collection chamber 1111 through the dust collection port 1112. Since the dust collection port 1112 is located at the top of the dirt collection chamber 111, waste can fall smoothly into the bottom of the dirt collection chamber 1111 by the combined action of gravity and airflow, without remaining at the interface. A sealing ring can be provided on the edge of the dust collection port 1112 to ensure airtightness when connected to the cup valve 22.

[0247] Furthermore, a separate valve is not required at the dust collection port 1112; instead, the opening and closing are controlled by the cup valves 22 on both sides of the cleaning equipment. This simplifies the structure of the sludge collection box 111 and reduces manufacturing costs. When the user needs to empty the waste from the sludge collection box 111, they only need to remove the sludge collection box 111 from the cleaning base station 1 and open the lid or bottom cover of the sludge collection box 111 to empty the waste. The dust collection port 1112 will not obstruct the emptying operation.

[0248] In some embodiments, continue to refer to Figure 4 As shown, the dust collection air path 1121 is formed inside the dust collection air duct 112, and the filter screen (not shown in the figure) is installed inside the dust collection air duct 112.

[0249] In this embodiment, by installing a filter screen (such as a HEPA filter) in the dust collection duct 112, the airflow after settling in the dust collection chamber 211 must undergo fine filtration before entering the negative pressure fan in dust collection mode. This effectively prevents fine dust from entering the negative pressure fan and causing motor wear or secondary pollution caused by being discharged into the room, protecting the fan, extending equipment life, and improving the cleanliness of the exhaust air.

[0250] For example, the dust collection duct 112 may be an independent channel formed on the side wall of the sludge collection box 111, with its inlet communicating with the upper space of the sludge collection chamber 1111 and its outlet extending to an interface area for docking with the handheld component 25. A filter screen may be disposed near the outlet of the dust collection duct 112, specifically a HEPA filter screen, a sponge filter element, or other materials with fine filtration function.

[0251] For example, in dust collection mode, the airflow after settling and separation in the dust collection chamber 1111 may still carry a small amount of fine dust. This airflow, after entering the dust collection duct 112, must pass through a filter screen before being drawn into the negative pressure fan. The filter screen effectively traps fine particles in the airflow, preventing them from entering the negative pressure fan and causing wear on the motor rotor or bearing jamming, thereby extending the service life of the negative pressure fan. At the same time, the filter screen also prevents this fine dust from being discharged into the indoor environment with the exhaust, causing secondary pollution.

[0252] In addition, since the dust collection duct 112 only flows through in dust collection mode, the water-containing airflow in floor washing mode does not flow through the dust collection duct 112. Therefore, the filter screen can always be kept dry, avoiding problems such as filter screen blockage, increased air resistance, or bacterial growth caused by moisture.

[0253] In some embodiments, such as Figure 1 As shown, the sewage inlet air passage 1141 is formed inside the sewage inlet pipe 114, and the sewage suction air passage 1221 is formed inside the sewage suction pipe 122.

[0254] In some embodiments, continuing to refer to the figures, the inlet pipe 114 is located inside the collection chamber 1111, the inlet valve 115 is disposed at the outlet of the inlet pipe 114, the inlet pipe 114 is sleeved on the suction pipe 122, and the outlet of the suction pipe 122 is exposed inside the inlet pipe 114.

[0255] In this embodiment, the inlet pipe 114 is placed inside the collection chamber 1111, and the inlet pipe 114 is fitted onto the suction pipe 122, with the outlet of the suction pipe 122 exposed inside the inlet pipe 114. After the water-containing airflow is ejected at high speed from the suction pipe 122, it initially expands and slows down within the inlet pipe 114, which has a sudden change in diameter, and then enters the larger collection chamber 1111 where it slows down and settles again. This "two-stage expansion" structure significantly enhances the water-air separation effect. The inlet valve 115 is located at the outlet of the inlet pipe 114, which can effectively seal the inlet path in dust collection mode to prevent backflow of airflow.

[0256] For example, the dirt collection assembly 11 includes a dirt inlet pipe 114, which is disposed inside the dirt collection chamber 1111, and its internal channels form a dirt inlet air passage 1141. A dirt inlet valve 115 is disposed at the outlet end of the dirt inlet pipe 114 and is used to control the opening and closing of the dirt inlet air passage 1141. The floor cleaning assembly 12 includes a suction pipe 122, the internal channels of which form a suction air passage 1221. The inlet of the suction pipe 122 communicates with the cleaning tank of the floor cleaning brush 121, and the outlet extends to the interface that connects with the dirt collection assembly 11.

[0257] In this embodiment, the inlet pipe 114 and the suction pipe 122 are connected by a sleeve connection: the inner diameter of the inlet pipe 114 is larger than the outer diameter of the suction pipe 122. When the sludge collection assembly 11 is connected to the floor cleaning assembly 12, the outlet end of the suction pipe 122 is inserted into the inlet end of the inlet pipe 114, so that the outlet of the suction pipe 122 is exposed inside the inlet pipe 114. This sleeve structure has multiple advantages: firstly, it achieves quick connection without the need for precise snap-fit ​​or threaded structures; secondly, the outlet of the suction pipe 122 is located inside the inlet pipe 114, which can prevent water-containing airflow from leaking out at the interface; thirdly, after the water-containing airflow is ejected at high speed from the suction pipe 122, it first enters the larger diameter inlet pipe 114, undergoes the first expansion and deceleration, and then enters the larger diameter sludge collection chamber 1111 from the outlet of the inlet pipe 114, undergoing the second expansion and deceleration. This "two-stage expansion" design enhances the water-air separation effect, allowing sewage and particles to settle more fully at the bottom of the collection chamber 1111, reducing the water vapor content entering the downstream pipeline.

[0258] In some embodiments, such as Figure 5 As shown, the exhaust air passage 1131 is formed inside the exhaust connector 113.

[0259] In some embodiments, such as Figure 6As shown, the intake air passage 2511 is formed inside the intake pipe 251, and the connecting air passage 2621 is formed inside the connecting pipe 262.

[0260] In some embodiments, continue to refer to Figure 4 As shown, in dust collection mode, the air intake pipe 251 is connected to the connecting pipe 262.

[0261] In some embodiments, continue to refer to Figure 5 As shown, in the floor cleaning mode, the air intake pipe 251 is connected to the exhaust connector 113.

[0262] In this embodiment, the air intake path 2511 is formed inside the air intake pipe 251, the connecting air path 2621 is formed inside the connecting pipe 262, and the exhaust air path 1131 is formed inside the exhaust connector 113. In dust collection mode, the air intake pipe 251 is connected to the connecting pipe 262, and in floor cleaning mode, the air intake pipe 251 is connected to the exhaust connector 113. This modular interface design allows the cleaning system to complete the air path reconfiguration simply by changing the connection object of the air intake pipe 251 when switching modes, without the need for complex pipe disassembly and assembly. This design constitutes the first and second forms of the cleaning device 2, which is convenient to operate and provides a good user experience.

[0263] For example, the sludge collection assembly 11 includes an exhaust connector 113, the internal channel of which forms an exhaust air passage 1131. The exhaust connector 113 is rotatably mounted on the side wall of the sludge collection box 111, and can be flipped inward and received within the outer contour of the sludge collection box 111 in dust collection mode, and can be flipped outward and protruded beyond the outer contour of the sludge collection box 111 in floor washing mode.

[0264] For example, the air intake pipe 251 is fixed inside the handheld assembly 25, and its internal channel forms an air intake passage 2511. The connecting pipe 262 is part of the vacuuming assembly 26, and its internal channel forms a connecting passage 2621.

[0265] For example, in dust collection mode, the cleaning device 2 is placed on the cleaning base station 1 in a first configuration. At this time, the air inlet pipe 251 of the handheld component 25 is connected to the connecting pipe 262 of the dust collection component 26, and the connecting air passage 2621 is connected to the air inlet air passage 2511. External airflow can enter the dust collection chamber 211 through the dust collection brush 261, the connecting air passage 2621, and the air inlet air passage 2511 to complete the dust collection operation.

[0266] For example, in the floor cleaning mode, the user detaches the vacuuming component 26 from the handheld component 25, and the cleaning device 2 is placed on the cleaning base station 1 in a second configuration. At this time, the air inlet pipe 251 of the handheld component 25 connects to the exhaust connector 113 of the dirt collection component 11, and the air inlet path 2511 is connected to the exhaust path 1131. The airflow in the dirt collection chamber 1111 can enter the dust collection chamber 211 through the exhaust path 1131 and the air inlet path 2511, completing the floor cleaning self-cleaning operation.

[0267] Thus, this modular interface design allows the cleaning system to reconfigure its entire airflow structure simply by changing the interface of the intake pipe 251 (e.g., connecting pipe 262 or exhaust connector 113) when switching modes. Users do not need to perform complex pipe disassembly or valve adjustments, making operation intuitive and convenient. Simultaneously, the cleaning device 2 thus achieves two interface configurations, corresponding to dust collection maintenance and floor cleaning maintenance respectively, clearly defining its functions.
