[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410704513.4, entitled "Cleaning Equipment and Cleaning System," filed with the China National Intellectual Property Administration on May 31, 2024, and Chinese Patent Application No. 202410704513.4, entitled "Cleaning Equipment and Cleaning System," both of which are incorporated herein by reference in their entirety. Technical Field

[0003] This disclosure relates to the field of cleaning technology, and in particular to a cleaning device and a cleaning system. Background Technology

[0004] Currently, cleaning systems typically include cleaning equipment (such as floor scrubbers and sweepers) and base stations. The cleaning equipment and base stations can use a dual-fan structure for wastewater treatment.

[0005] More specifically, the cleaning equipment can be equipped with a main fan and a main wastewater tank, while the base station can be equipped with a base station fan and a base station wastewater tank. During mopping or self-cleaning operations, the main fan on the cleaning equipment is turned on, creating negative pressure in the main wastewater tank to draw wastewater from the cleaning components (such as roller brushes and mopping discs) into it. When the cleaning equipment is connected to a base station, the base station fan is turned on, creating negative pressure in the base station wastewater tank to draw wastewater from the main wastewater tank into it, thus automatically cleaning the main wastewater tank. However, this dual-fan structure is relatively complex, costly, and inconvenient to install and maintain.

[0013] In one embodiment, the first reversing housing, the second reversing housing, the first movable member, and the second movable member are coaxially arranged.

[0014] In one embodiment, the movable member is rotatably engaged with the reversing housing; the airflow reversing structure further includes: a reversing drive assembly, which is drivenly connected to the movable member and is used to drive the movable member to rotate, so that the airflow reversing structure presents the first conduction state or the second conduction state.

[0015] In one embodiment, the cleaning device is provided with a sewage inlet pipe, and a sewage suction cover is provided at the sewage outlet of the sewage inlet pipe; when the airflow reversing structure is in the first conducting state, the sewage suction cover is in an open state, allowing sewage to enter the main unit's sewage tank; when the airflow reversing structure is in the second conducting state, the sewage suction cover is in a closed state, sealing the sewage outlet.

[0016] In one embodiment, the cleaning device further includes a drain switch structure, which closes the drain port when the airflow reversing structure is in the first conducting state, and opens the drain port when the airflow reversing structure is in the second conducting state.

[0017] Secondly, this disclosure provides a cleaning system, comprising: a cleaning device, the cleaning device including a body, a suction device, a main unit wastewater tank, a drain outlet, and an airflow reversing structure, the airflow reversing structure having a second conductive state; and a base station, the base station including a wastewater collection port; when the cleaning device is connected to the base station, the drain outlet and the wastewater collection port are connected, and when the airflow reversing structure is in the second conductive state, the suction device pressurizes the wastewater tank of the main unit to discharge the wastewater in the wastewater tank of the main unit to the base station through the drain outlet.

[0020] The aforementioned cleaning equipment and system are equipped with a suction device and an airflow reversing structure. Under the action of the airflow reversing structure, the main unit's wastewater tank can be in a negative pressure state, thereby sucking wastewater into the main unit's wastewater tank; or it can be in a pressurized state, thereby discharging the wastewater in the main unit's wastewater tank to external equipment. That is, based on the single fan structure of the cleaning equipment, both the suction and discharge needs can be met, making the structure of the cleaning system simpler, the cost lower, and the assembly and maintenance more convenient.

[0021] Furthermore, by using a pressurization method to discharge the sewage from the host sewage tank, the base station does not need to be in a negative pressure state, that is, the automatic sewage collection function can be realized without setting up air ducts in the base station, which greatly simplifies the structure of the base station.

[0047] Example 1

[0048] This disclosure provides a cleaning device 10, which can be a passive floor cleaning device (such as a floor scrubber), a vacuum cleaner, an automatic floor cleaning device (such as a sweeper), a window cleaning machine, etc. As shown in Figures 1 and 2, taking a floor scrubber as an example, the cleaning device 10 includes a handle 110, a body 120, a floor brush assembly 130 pivotally connected to the body 120, etc. The body 120 may be equipped with, but is not limited to, a water tank and a power assembly 160.

[0049] The floor brush assembly 130 may include a floor brush housing, cleaning components, a floor brush motor, and a water spray assembly. The cleaning components, such as a mop disc, mopping roller, or sweeping side brush, are used to clean surfaces (e.g., floors, carpets, windows). The power assembly 160 may include a power handle and a power housing. The power housing may house a battery pack, a suction device 170, a noise reduction structure, a heat dissipation structure, and a shock absorption structure. The suction device 170 may be a fan. The water tank includes a main unit clean water tank 140 and a main unit waste water tank 150.

[0050] Referring again to Figure 1, with the default direction of travel of the cleaning equipment 10 as the front and the user-facing side as the rear, the power unit 160, the main unit clean water tank 140, and the main unit wastewater tank 150 are located on the same side of the body 120, preferably at the rear of the body 120. Vertically, the power unit 160, the main unit clean water tank 140, and the main unit wastewater tank 150 are arranged sequentially from top to bottom. This arrangement reduces the overall size of the cleaning equipment 10, making the machine lighter and more compact.

[0051] As shown in Figures 2 and 3, the cleaning device 10 is equipped with a sewage inlet pipe (not shown in the figures). The sewage inlet pipe can be located inside or adjacent to the main unit's sewage tank 150. The sewage inlet pipe has an outlet. The sewage inlet pipe connects to the floor brush assembly 130, enabling the cleaning device 10 to have a sewage suction mode. In the sewage suction mode, sewage flows into the main unit's sewage tank 150 through the sewage outlet of the sewage inlet pipe. The main unit's sewage tank 150 is equipped with a sewage outlet 153, enabling the cleaning device 10 to have a sewage discharge mode. In the sewage discharge mode, the sewage in the main unit's sewage tank 150 can be discharged to the outside of the cleaning device 10, such as to the base station 20 to which the cleaning device 10 is adapted.

[0052] Optionally, the drain outlet 153 can be located at any position, such as the rear side or bottom of the main unit's wastewater tank 150. In this embodiment, the drain outlet 153 is preferably located at the bottom of the main unit's wastewater tank 150.

[0053] In one embodiment, as shown in Figures 4 to 7, the cleaning device 10 further includes an airflow reversing structure 180, which can be disposed in the power housing and adjacent to the suction device 170. Preferably, the airflow reversing structure 180 is installed below the suction device 170 to change the airflow direction of the suction device 170, so that the cleaning device 10 has a suction mode and a discharge mode.

[0054] Specifically, the airflow reversing structure 180 has a first conducting state and a second conducting state. As shown in Figure 5, in the first conducting state, the cleaning device 10 enters the suction mode. The airflow reversing mechanism 180 has an airflow inlet and an airflow outlet, allowing the airflow in the main unit's wastewater tank 150 to enter the airflow reversing structure 180 through the airflow inlet, and then enter the air intake end of the suction device 170, and finally be discharged to the outside atmosphere from the air outlet end of the suction device 170. The main unit's wastewater tank 150 is under negative pressure, which sucks the wastewater generated by the floor brush assembly 130 into the main unit's wastewater tank 150.

[0055] In the second conduction state, as shown in Figures 4 and 6, the cleaning device 10 enters the sewage discharge mode. The airflow reversing structure 180 has an airflow inlet and an airflow outlet. External air enters the airflow reversing structure 180 through the airflow inlet, then enters the air intake end of the suction device 170, and is discharged from the air outlet end of the suction device 170 to the airflow reversing structure 180. The airflow is redirected in the airflow reversing structure 180 and finally discharged from the airflow outlet of the airflow reversing structure 180 and enters the main unit sewage tank 150 to pressurize the main unit sewage tank 150, causing the sewage in the main unit sewage tank 150 to be discharged to the outside from the sewage outlet 153.

[0056] Specifically, as shown in Figures 7 to 13, the airflow reversing structure 180 includes a reversing housing 1813, which is provided with a first air inlet 1831, a second air inlet 1832, a first air outlet 1811, and a second air outlet 1833.

[0057] A first airflow passage can be formed between the first air inlet 1831 and the first air outlet 1811. The first air inlet 1831 is connected to the main unit's wastewater tank 150, and the first air outlet 1811 is connected to the outside air. When the first air inlet 1831 and the first air outlet 1811 are connected, the airflow reversing structure 180 is in a first conducting state. Under the action of the suction device 170, the air in the main unit's wastewater tank 150 can enter the first airflow passage through the first air inlet 1831 and flow out to the outside air from the first air outlet 1811, causing negative pressure in the main unit's wastewater tank 150.

[0058] A second airflow passage can be formed between the second air inlet 1832 and the second air outlet 1833. The second air inlet 1832 is connected to external air, and the second air outlet 1833 is connected to the main unit's wastewater tank 150. When the second air inlet 1832 and the second air outlet 1833 are connected, the airflow reversing structure 180 is in a second conducting state. Under the action of the suction device 170, external air enters the second airflow passage through the second air inlet 1832 and flows out from the second air outlet 1833, and then enters the main unit's wastewater tank 150, thereby pressurizing the main unit's wastewater tank 150.

[0059] Optionally, the first air inlet 1831 and the second air inlet 1832 are located near the air inlet end of the suction device 170. This shortens the airflow path into the suction device 170, reduces airflow loss, and improves the efficiency of suction and discharge. Correspondingly, the first air outlet 1811 and the second air outlet 1833 can also be located near the air outlet end of the suction device 170.

[0060] Optionally, through holes are provided on the power housing at positions corresponding to the first air outlet 1811 and the second air inlet 1832, so that external air can enter the second air inlet 1832 through the through holes, and the airflow inside the cleaning device 10 can flow to the outside through the through holes corresponding to the first air outlet 1811.

[0061] Optionally, the first air inlet 1831 and the second air outlet 1833 can be the same or different; the second air inlet 1832 and the first air outlet 1811 can be the same or different.

[0062] In this embodiment, an airflow reversing structure 180 is provided on the cleaning device 10. Based on the suction device 170 inside the cleaning device 10, both the suction mode and the discharge mode can be realized, thereby making the structure of the cleaning system simpler, the cost lower, and the assembly and maintenance more convenient.

[0063] In one embodiment, as shown in Figures 4, 7, and 8-11, the reversing housing 1813 includes a first reversing housing 181 and a second reversing housing 183. The first reversing housing 181 and the second reversing housing 183 can be separately arranged or integrally arranged. In the vertical direction, the second reversing housing 183 is located below the first reversing housing 181. The first reversing housing 181 has a hollow frame that accommodates the suction device 170, and a first air outlet 1811 is provided on the first reversing housing 181. As shown in Figure 8, there can be multiple first air outlets 1811, which are spaced apart on the sidewall of the first reversing housing 1811.

[0064] As shown in Figures 9-11, a first air inlet 1831, a second air inlet 1832, and a second air outlet 1833 are disposed on the second reversing housing 183. Specifically, the second reversing housing 183 includes a cavity 1836 and a reversing outer shell 1837 surrounding the cavity, wherein the cavity 1836 and the reversing outer shell 1837 are spaced apart, forming a first receiving space at the gap. Preferably, the cavity 1836 is directly opposite the air inlet end of the suction device 170. The first air inlet 1831 is disposed at the bottom of the cavity 1836, so that the airflow entering from the first air inlet 1831 can enter the suction device 170 in a straight path, thereby reducing airflow loss. As shown in Figure 11, there can be multiple first air inlets 1831, which are spaced apart. Preferably, the multiple first air inlets 1831 are fan-shaped and spaced apart around the same center, which can be the center of the bottom of the cavity 1836.

[0065] The second air inlet 1832 is disposed on the reversing housing 1837 of the second reversing housing 183. Furthermore, an opening 1835 is also provided on the side wall of the cavity 1836 at a position corresponding to the second air inlet 1832, allowing external air to enter the cavity 1836 through the second air inlet 1832 and the opening 1835 on the side wall of the cavity 1836, and subsequently into the air intake end of the suction device 170. As shown in Figure 9, there can be multiple second air inlets 1832, spaced apart. Correspondingly, the side wall of the cavity 1836 also has an opening 1835 corresponding to each second air inlet 1832.

[0066] The second air outlet 1833 is located on the upper surface of the second reversing housing 183 and extends downward along the axial direction of the second reversing housing 183 to the bottom of the second reversing housing 183, forming an axial airflow channel on the second reversing housing 183. As shown in Figures 9 to 11, there can be multiple second air outlets 1833. Multiple second air outlets 1833 are arranged around the same center and extend in an arc through the upper and lower surfaces of the second reversing housing 183. That is, the reversing housing 1837 of the second reversing housing 183 has multiple axially extending airflow channels.

[0067] In one embodiment, the airflow reversing structure 180 further includes a movable member 1826, which cooperates with the reversing housing 1813 of the airflow reversing structure 180 and includes a first conducting structure and a second conducting structure. When one of the first conducting structure and the second conducting structure is in a conducting state, the other is in a blocking state.

[0068] Specifically, the first conductive structure cooperates with the first air inlet 1831 and the first air outlet 1811. When the airflow reversing structure 180 is in the first conductive state, the first conductive structure can connect the first air inlet 1831 and the first air outlet 1811, allowing airflow from the first air inlet 1831 and the first air outlet 1811 into the suction device 170. At the same time, the second conductive structure cannot connect the second air inlet 1832 and the second air outlet 1833.

[0069] When the airflow reversing structure 180 is in the second conducting state, the second conducting structure can connect the second air inlet 1832 and the second air outlet 1833, allowing the second air inlet 1832 and the second air outlet 1833 to circulate, and external air enters the suction device 170 and then enters the main unit's sewage tank 150. At the same time, the first conducting structure cannot connect the first air inlet and the first air outlet.

[0070] Optionally, the first conduction structure and / or the second conduction structure can be implemented based on a solenoid valve, connecting rod, reciprocating mechanical structure, etc.

[0071] In this embodiment, a movable component 1826 is provided in the airflow reversing structure. Two airflow paths can be realized through this single component, which greatly simplifies the structure of the cleaning equipment.

[0072] In one embodiment, as shown in Figures 7 and 12-13, the first conductive structure includes a first pair of interfaces 1841 and a second pair of interfaces 1821, and the second conductive structure includes a third pair of interfaces 1842 and a fourth pair of interfaces 1843. Specifically, the first pair of interfaces 1841 is used to connect with the first air inlet 1831, the second pair of interfaces 1821 is used to connect with the first air outlet 1811, the third pair of interfaces 1842 is used to connect with the second air inlet 1832, and the fourth pair of interfaces 1843 is used to connect with the second air outlet 1833.

[0073] Specifically, when the airflow reversing structure 180 is in the first conducting state, the first pair of interfaces 1841 is connected to the first air inlet 1831, and the second pair of interfaces 1821 is connected to the first air outlet 1811. At the same time, the third pair of interfaces 1842 cannot be connected to the second air inlet 1832, and the fourth pair of interfaces 1843 cannot be connected to the second air outlet 1833. As a result, the airflow flows out of the main unit sewage tank 150 through the first air inlet 1831 to the suction device 170, but cannot enter the main unit sewage tank 150 from the suction device 170 through the second air inlet 1832.

[0074] Correspondingly, when the airflow reversing structure 180 is in the second conducting state, the first pair of interfaces 1841 cannot be connected to the first air inlet 1831, the second pair of interfaces 1821 cannot be connected to the first air outlet 1811, and at the same time, the third pair of interfaces 1842 is connected to the second air inlet 1832, and the fourth pair of interfaces 1843 is connected to the second air outlet 1833, so that external air enters the suction device 170 through the second air inlet 1832 and then flows out to the main unit sewage tank 150 through the second air outlet 1833.

[0075] In one embodiment, referring to Figures 7, 12, and 13, the movable member 1826 includes a first movable member 182 and a second movable member 184. The first movable member 182 is fitted with the first reversing housing 181 and sleeved on the outside of the first reversing housing 181, covering the first air outlet 1811. A second pair of interfaces 1821 is provided on the first movable member 182. When the first reversing housing 181 has multiple first air outlets 1811, the first movable member 182 also has multiple pairs of second interfaces 1821 accordingly.

[0076] The second movable member 184 is configured to cooperate with the second reversing housing 183. The second movable member 184 is open at the top and bottom, and its outer wall is divided into a first part and a second part (not shown in the figure) by a partition 1847. The first part is located above the second part. The first part and the partition 1847 form a second receiving space. The cavity 1836 of the second reversing housing 183 is adapted to be received in the second receiving space, such that the bottom of the partition 1847 is directly opposite to the bottom of the cavity 1836.

[0077] The first pair of interfaces 1841 are disposed on the partition 1847, and their shape and size can be adapted to the first air inlet 1831. For example, if the first air inlet 1831 is square, the first pair of interfaces 1841 also adopts a square shape of the same size, so that the airflow can be transmitted to the suction device 170 as much as possible and reduce airflow loss. Of course, when there are multiple first air inlets 1831, there are also multiple first pairs of interfaces 1841, and multiple first pairs of interfaces 1841 correspond one-to-one with multiple first air inlets 1831.

[0078] The outer wall of the first part of the second movable member 184 is adapted to be accommodated in a first receiving space formed between the reversing housing 1837 and the cavity 1836 of the second reversing housing 183, that is, the second movable member 184 and the second reversing housing 183 can be assembled in a plug-in manner.

[0079] The third pair of interfaces 1842 is disposed on the outer wall of the first part to mate with the second air inlet 1832 on the second reversing housing 183. Its shape and size can be adapted to the second air inlet 1832. For example, if the second air inlet 1832 is square, the third pair of interfaces 1842 is also square of the same size, thereby reducing airflow loss.

[0080] The fourth pair of interfaces 1843 is disposed on the outer wall of the second part to be compatible with the second air outlet 1833 of the second reversing housing 183. In this embodiment, the airflow channel extending axially from the second air outlet 1833 has an outer wall and an inner wall, wherein the length of the inner wall is less than the length of the outer wall, that is, the inner wall cannot reach the bottom of the fourth pair of interfaces 1843, so that after the second movable part 184 and the second reversing housing 183 are assembled, the fourth pair of interfaces 1843 will not be covered by the inner wall and block the airflow.

[0081] In one embodiment, as shown in FIG7, the first reversing housing 181, the second reversing housing 183, the first movable member 182, and the second movable member 184 are coaxial. A shock-absorbing pad, sound-absorbing cotton, or other structure is provided between the first reversing housing 181 and the suction device 170 to reduce vibration and noise generated by the operation of the suction device 170. A first sealing structure 186 may be provided between the first reversing housing 181 and the first movable member 182 to seal the gap between them; this first sealing structure 186 may be an integral structure. A second sealing structure 187 may be provided between the second reversing housing 183 and the second movable member 184 to seal the gap between them; this second sealing structure 187 may be an integral structure.

[0082] In one embodiment, as shown in Figures 4 and 7, the airflow reversing structure 180 includes a reversing drive assembly 1825. This reversing drive assembly 1825 may include a reversing drive member 185 and a reversing transmission member 188 drivenly connected to the reversing drive member 185. The reversing transmission member 188 is drivenly connected to a movable member 1826, and under the action of the reversing drive member 185, drives the movable member 1826 to move, causing the airflow reversing structure 170 to present a first conducting state or a second conducting state. The reversing drive member 185 may be a motor.

[0083] Specifically, as shown in Figures 4, 7, 8, 12 and 13, the reversing transmission member 188 includes a first transmission member 1822 and a second transmission member 1823. The first transmission member 1822 and the second transmission member 1823 are disposed on the first movable member 182. The first transmission member 1822 is used to drive the first movable member 182 to rotate, and the second transmission member 1823 is used to drive the second movable member 184 to rotate.

[0084] The first transmission component 1822 can adopt a structure such as a gear or a transmission belt. Taking a gear as an example, the output end of the reversing drive component 185 is provided with a gear structure that is compatible with the first transmission component 1822. When the reversing drive component 185 is working, it can drive the first movable component 182 to rotate through the gear structure.

[0085] The second transmission member 1823 is connected to the second movable member 184 in a transmission manner. The second transmission member 1823 may be a protruding rib extending to the second movable member 184, and the protruding rib is provided with a first mating part (not shown in the figure). The second movable member 184 is provided with a second mating part 1846 that locks with the first mating part. When the reversing drive member 185 drives the first movable member 182 to rotate, the second transmission member 1823 rotates accordingly, and the second movable member 184 also rotates under the drive of the first mating part and the second mating part 1846, thereby causing the airflow reversing structure 180 to be in a first conducting state or a second conducting state.

[0086] Optionally, as shown in Figures 7 and 8, the first commutation housing 181 is provided with an outward protrusion 1812, which has a receiving groove suitable for accommodating the commutation drive 185.

[0087] By adopting the aforementioned drive reversing assembly 1825, two moving parts 1826 can be driven to rotate synchronously under the drive of a single reversing drive 185, saving costs and simplifying the structure.

[0088] In one embodiment, as shown in FIG10, the airflow reversing structure 180 further includes a limiting structure 1834, which is disposed on the second reversing housing 183. A second mating part 1846 can extend from the limiting structure 1834 to limit the maximum rotation angle of the reversing drive member 185, the first movable member 182, and the second movable member 184 through the cooperation of the second mating part 1846 and the limiting structure 1834, so as to avoid abnormal operation of the airflow reversing structure 180 due to reasons such as failure of the reversing drive member 185.

[0089] In one embodiment, as shown in Figures 12 and 13, a second sealing structure 1824 is provided on the first movable member 182, which is used to seal the first air outlet 1811. The second sealing structure 1824 can be arranged adjacent to the second pair of interfaces 1821. When there are multiple first air outlets 1811 and multiple pairs of interfaces 1821, there are also multiple second sealing structures 1824, forming multiple second sealing structures 1824 between two adjacent pairs of first interfaces 1821.

[0090] The second movable component 184 is provided with a first sealing structure 1844, a third sealing structure 1845, and a fourth sealing structure 1848. The first sealing structure 1844 is disposed adjacent to the first pair of interfaces 1841 and is used to seal the first air inlet 1831. When there are multiple first air inlets 1831 and multiple first pair of interfaces 1841, there are also multiple first sealing structures 1844, which are formed between two adjacent first pair of interfaces 1841.

[0091] The third sealing structure 1845 is arranged adjacent to the third pair of interfaces 1842 and is used to seal the second air inlet 1832. When there are multiple second air inlets 1832 and multiple third pairs of interfaces 1842, there are also multiple third sealing structures 1845, which are formed between two adjacent third pairs of interfaces 1842.

[0092] The fourth sealing structure 1848 is arranged adjacent to the fourth pair of interfaces 1843 and is used to seal the second air outlet 1833. When there are multiple second air outlets 1833 and multiple fourth pair of interfaces 1843, there are also multiple fourth sealing structures 1848, which are formed between two adjacent fourth pair of interfaces 1843.

[0093] Specifically, the airflow reversing structure 180 also includes a position sensor (not shown in the figure), which can be implemented using a micro switch, Hall sensor, etc. When the cleaning device 10 enters the suction mode, if the controller on the cleaning device 10 determines that the airflow reversing structure 180 is not currently in the first conducting state based on the position detection signal of the position sensor, it controls the reversing drive 185 to rotate a preset angle along the first direction, so as to drive the first movable part 182 and the second movable part 184 to rotate synchronously, so that the airflow reversing structure 180 presents the first conducting state. At this time, the third sealing structure 1845 on the second movable part 184 blocks the second air inlet 1832, and the fourth sealing structure 1848 blocks the second air outlet 1833, so that external air cannot enter the cleaning device 10. Meanwhile, the second pair of interfaces 1821 on the first movable component 182 connects to the first air outlet 1811 on the first reversing housing 181, and the first pair of interfaces 1841 on the second movable component 184 connects to the first air inlet 1831 at the bottom of the second reversing housing 183, so that the air in the main unit sewage tank 150 can enter the suction device 170 from the first air inlet 1831 and be discharged to the external environment from the first air outlet 1811 on the side wall of the first reversing housing 181.

[0094] Correspondingly, when the cleaning equipment 10 enters the sewage discharge mode, if the controller determines that the airflow reversing structure 180 is not currently in the second conduction state based on the position detection signal of the position sensor, it controls the reversing drive 185 to rotate by a preset angle along the second direction, driving the first movable part 182 and the second movable part 184 to rotate synchronously, so that the airflow reversing structure 180 presents the second conduction state. At this time, the second blocking structure 1824 on the first movable part 182 is connected to the first air outlet 1811 on the first reversing housing 181; the first blocking structure 1844 on the second movable part 184 is connected to the first air inlet 1831 at the bottom of the second reversing housing 183, so as to block the airflow outflow path of the main unit sewage tank 150. Meanwhile, the third pair of interfaces 1842 on the second movable part 184 connects to the second air inlet 1832 on the second reversing housing 183, and the fourth pair of interfaces 1843 on the second movable part 184 connects to the second air outlet 1833 on the second reversing housing 183, so that external air flows from the second air inlet 1832 into the airflow reversing structure 180, and reaches the main unit sewage tank 150 through the suction device 170, causing the sewage in the main unit sewage tank 150 to be discharged.

[0095] The first and second directions mentioned above are opposite directions. For example, the first direction is counterclockwise, and the second direction is clockwise.

[0096] In this embodiment, by setting a position sensor and a blocking structure, the airflow reversing structure can be fully automatically controlled based on the circuit system of the position sensor, controller and drive motor, thereby improving the intelligence level of the cleaning equipment.

[0097] In one embodiment, as shown in Figures 2, 13, and 14, the main unit's wastewater tank 150 is provided with a wastewater inlet pipe. A suction switch structure is provided at the wastewater outlet of the inlet pipe to open or close the wastewater outlet. The suction switch structure may include a suction drive and a suction cover 151. The suction cover 151, under the driving force of the suction drive, has an open state (opening the wastewater outlet) and a closed state (closing the wastewater outlet). When the cleaning device 10 executes the suction mode, the airflow reversing structure 180 is in a first conducting state, and the suction drive causes the suction cover 151 to open, allowing wastewater to enter the main unit's wastewater tank 150 through the inlet pipe. When the cleaning device 10 executes the discharge mode, the airflow reversing structure 180 is in a second conducting state, and the suction drive causes the suction cover 151 to close, preventing wastewater from entering the main unit's wastewater tank 150. Simultaneously, it prevents the airflow entering the main unit's wastewater tank 150 from flowing out of the inlet pipe, thereby improving the pressurization efficiency of the main unit's wastewater tank 150.

[0098] Optionally, when the cleaning device 10 is in the sewage discharge mode, the suction drive can also cause the suction cover 151 to open.

[0099] Optionally, the suction drive can be a motor, and the suction cover 151 can switch between an open state and a closed state under the action of electric driving force.

[0100] Optionally, the suction drive component can be an elastic element, such as a spring or torsion spring, and the suction cover 151 can switch between an open and closed state under the action of an elastic restoring force. Specifically, as shown in Figure 14, when the cleaning device 10 is in suction mode, the main unit's wastewater tank 150 is under negative pressure, and the suction cover 151 overcomes the elastic restoring force of the elastic element and flips upward to the open state. As shown in Figure 2, when the cleaning device 10 is in discharge mode, the main unit's wastewater tank 150 is under positive pressure, and the suction cover 151 flips downward to the closed state under the action of the elastic restoring force and the positive pressure. This method has a simple mechanical structure and can also simplify the electrical control circuit of the cleaning device 10.

[0101] Alternatively, the suction cover 151 can be made of soft rubber. Soft rubber has good sealing performance and is lightweight, which improves the sealing performance between the floor brush assembly 130 and the main unit's wastewater tank 150, while also making it easier to flip over.

[0102] In one embodiment, the cleaning device 10 further includes a drain switch structure that cooperates with the drain outlet 153 to open or close the drain outlet 153. The drain switch structure includes a drain drive (not shown) and a drain plug connected to the drain drive. The drain drive can be a motor. The drain plug is connected to both the drain drive and the main unit's wastewater tank 150, and under the drive of the drain drive, has an open state (open drain outlet 153) and a closed state (closed drain outlet 153).

[0103] Specifically, as shown in Figures 2 and 3, the sewage sealing component includes a sewage transmission component 155 and a sewage cover 156. The sewage transmission component 155 can be rod-shaped, with one end connected to the sewage drive component and the other end connected to the sewage cover 156. The sewage cover 156 is pivotally connected to the sewage outlet 153. When the cleaning equipment 10 operates in the suction mode, the sewage drive component can rotate in a third direction, causing the sewage transmission component 155 to move closer to the sewage outlet 153, thereby causing the sewage cover 156 to close, thus sealing the sewage outlet 153 and preventing sewage from flowing out of the sewage outlet 153. When the cleaning equipment 10 operates in the sewage discharge mode, the sewage drive component can rotate in a fourth direction, causing the sewage transmission component 155 to move away from the sewage outlet 153. The sewage cover 156 can open under gravity, allowing sewage to be discharged through the sewage outlet 153 under positive pressure and gravity. The third and fourth directions mentioned above are opposite directions. For example, the third direction is counterclockwise, while the fourth direction is clockwise.

[0104] Optionally, in some scenarios, such as self-cleaning scenarios, when the cleaning device 10 performs self-cleaning on the cleaning components and is in the suction mode, the sewage discharge drive can drive the sewage discharge cover 156 to open, so that the sewage generated during the self-cleaning process can be discharged directly through the sewage discharge port 153.

[0105] Optionally, the sewage discharge drive component and sewage discharge transmission component 155 are embedded in the body 120. In this way, the space of the body 120 can be effectively utilized, which is conducive to the miniaturization of the cleaning equipment 10.

[0106] Optionally, the sewage discharge drive and the controller are electrically connected. In one example, when the controller determines that a sewage suction mode needs to be executed, it sends a closing signal to the sewage discharge drive, causing the sewage discharge drive to move the sewage discharge cover 156 to the closed state. When the controller determines that a sewage discharge mode needs to be executed, it sends an opening signal to the sewage discharge drive, causing the sewage discharge drive to move the sewage discharge cover 156 to the open state, thereby making the cleaning equipment 10 more intelligent.

[0107] Example 2

[0108] This disclosure provides a cleaning system. The cleaning system can be a passive floor cleaning system (such as a floor scrubber), a vacuum cleaner, an automatic floor cleaning system (such as a sweeper), a window cleaning machine, etc. As shown in Figures 1, 2, 15, and 16, taking a floor scrubber as an example, the cleaning system includes a cleaning device 10 and a base station 20. The base station 20 may be equipped with a tray 210 and a base station body 220 extending along the height direction. The base station 20 may be equipped with a base station water replenishment component, a base station sewage discharge component, a charging component, etc. The base station 20 is also equipped with a sewage collection port 221. When the cleaning device 10 is connected to the base station 20, under the action of the sewage discharge drive, the sewage in the main unit's sewage tank 150 is automatically discharged into the base station 20 through the sewage discharge port 153 and the sewage collection port 221.

[0109] Alternatively, the charging component can be wireless charging, a charging terminal, etc.

[0110] Optionally, the base station water replenishment component may include a base station clean water tank and a water injection component. The base station clean water tank is used to store cleaning solution. After the cleaning device 10 is connected to the base station 20, the cleaning solution in the base station clean water tank is automatically injected into the main unit clean water tank 140 through the water injection component. Of course, the base station water replenishment component may also not have a base station clean water tank. Instead, a solenoid valve is used to connect the water injection component and the tap water pipe. When the cleaning device 10 needs water replenishment, the solenoid valve is opened, allowing the water injection component to directly inject tap water or a cleaning solution mixed with cleaning agent into the main unit clean water tank 140 through the injection port 222. This method simplifies the structure of the base station 20.

[0111] Optionally, the base station sewage discharge assembly may include a base station sewage tank 225 and a sewage collection port 221. When the cleaning equipment 10 is connected to the base station 20 and in sewage discharge mode, sewage enters the base station sewage tank 225 through the sewage collection port 221.

[0112] Optionally, the base station wastewater tank 225 can be connected to an automatic drainage structure. When wastewater enters the base station wastewater tank 225, the automatic drainage structure opens, and the wastewater is automatically discharged into the municipal pipeline, thus achieving fully automated wastewater treatment without requiring manual treatment by the user. Of course, the base station sewage discharge component may also exclude the base station wastewater tank 225, and instead connect the sewage collection port 221 directly to the automatic drainage structure, allowing wastewater to be discharged into the municipal pipeline in real time through the sewage collection port 221 and the automatic drainage structure.

[0113] Optionally, the base station sewage discharge assembly also includes a sewage collection pipe 224, one end of which is connected to a sewage collection port 221, and the other end is connected to a base station sewage tank 225. Sewage is introduced into the base station sewage tank 225 through the sewage collection pipe 224. Since the above embodiment uses positive pressure for sewage discharge, the sewage collection pipe 224 provides a certain pressure relief space for the sewage, thus avoiding damage to the sewage discharge path on the base station 20.

[0114] Optionally, the sewage inlet of the base station sewage tank 225 can be located above the base station sewage tank 225, so that the sewage flows from top to bottom inside the base station sewage tank 225 to flush the inner wall of the base station sewage tank 225.

[0115] Optionally, the base station 20 also includes a base station spray structure (not shown in the figure), which can be located near the cover of the base station wastewater tank 225 for automatically cleaning the inner wall of the base station wastewater tank 225.

[0116] Optionally, the inner wall of the base station wastewater tank 225 may also be provided with a flow guiding structure. This flow guiding structure extends from the top to the bottom of the base station wastewater tank 225, allowing the cleaning liquid or wastewater entering the base station wastewater tank 225 to be guided by the flow guiding structure to flush the entire inner wall, which helps maintain the cleanliness of the base station wastewater tank 225. The flow guiding structure can be a vortex structure.

[0117] In one embodiment, the base station 20 is also equipped with a pressure relief structure (not shown in the figure) to reduce the internal pressure of the base station 20. Specifically, when positive pressure sewage discharge is used, the pressure inside the base station 20 also increases during the sewage discharge process. Excessive pressure can easily cause damage to the pipes or automatic drainage structure in the base station 20. By setting a pressure relief structure inside the base station 20, the pressure inside the base station 20 can be reduced, and the service life of the base station 20 can be extended.

[0118] Optionally, the pressure relief structure includes at least one through hole, which can be provided on the base station sewage tank 225 to connect the inside of the base station sewage tank 225 with the outside atmosphere. During sewage discharge, the pressure in the base station sewage tank 225 can be reduced, thereby reducing the impact force on the automatic drainage structure.

[0119] Optionally, the pressure relief structure includes a pressure relief valve, which can be located at any position such as the sewage collection pipe 224 or the base station sewage tank 225. The pressure relief valve can be electrically controlled. In one example, a preset pressure is pre-set in the controller, which is equal to or slightly greater than atmospheric pressure. During sewage discharge, the controller controls the pressure relief valve to release pressure until the pressure inside the base station 20 equals the preset pressure, so that the pressure inside the base station 20 is atmospheric pressure or in a slightly positive pressure state. This helps to improve the sewage discharge efficiency of the base station 20 without putting too much pressure on the automatic drainage structure.

[0120] In one embodiment, as shown in FIG2, a host spray structure 152 is provided on the top of the host wastewater tank 150. In this embodiment, a spray pipe 141 is provided inside the host clean water tank 140, which extends upward from the bottom of the host clean water tank 140. The spray pipe 141 has a hollow structure and has a first end and a second end, wherein the first end is close to the top cover of the host clean water tank 140, and the second end is connected to the host spray structure 152. When the host wastewater tank 150 needs to be self-cleaned, the controller controls the liquid injection component on the base station 20 to inject cleaning liquid into the host clean water tank 140 until the liquid level of the cleaning liquid is higher than the first end of the spray pipe 141, so that the cleaning liquid flows in from the first end and flows out from the second end to the host spray structure 152, so that the host spray structure 152 self-cleans the host wastewater tank 150.

[0121] Optionally, the main unit's clean water tank 140 may be equipped with a full-fill detection mechanism, which can be implemented using conductive electrodes, optical sensors, etc. When the controller detects that the main unit's clean water tank 140 is full through the full-fill detection mechanism, it controls the liquid injection component to shut down. Correspondingly, the main unit's wastewater tank 150 and the base station's wastewater tank 225 may also be equipped with full-fill detection mechanisms. When the controller detects that the main unit's wastewater tank 150 and / or the base station's wastewater tank 225 is full through the full-fill detection mechanism, it can issue a prompt message.

[0122] Optionally, the cleaning device 10 may be equipped with a water shortage detection mechanism, which may be implemented using optical sensors or the like. When the controller detects that the main unit's clean water tank 140 is short of water through the water shortage detection mechanism, it may issue a prompt message.

[0123] In one embodiment, the main unit's clean water tank 140 and main unit's wastewater tank 150 can be locked together by a locking mechanism 158 and disassembled integrally from the main unit 120. The locking mechanism 158 has a locked state and an unlocked state. After disassembly, the locking mechanism 158 can be operated to lock or separate the main unit's clean water tank 140 and main unit's wastewater tank 150.

[0124] In one embodiment, as shown in FIG2, the gas path of the cleaning device 10 in the suction mode is further provided with a gas-liquid separation component 157. The gas-liquid separation component 157 may be, but is not limited to, a HEPA filter, a sponge, etc., for gas-liquid separation in the suction mode.

[0125] Optionally, referring to Figure 2, an airflow channel is provided between the front of the main unit's clean water tank 140 and the main body 120. In the suction mode, the downstream of this airflow channel connects to the main unit's wastewater tank 150, and the upstream connects to the power unit 160. The gas-liquid separation component 157 is disposed in the airflow channel, preferably upstream. This approach extends the path of the gas-liquid mixture to the gas-liquid separation component 157, allowing the mixture to undergo gas-liquid separation once in the airflow channel and then a second gas-liquid separation in the gas-liquid separation component 157, thereby improving the gas-liquid separation effect.

[0126] Optionally, the gas-liquid separation assembly 157 may also include an impeller, which, by providing power to the gas-liquid mixture, helps to further improve the gas-liquid separation effect.

[0127] Example 3

[0128] The following description, in conjunction with Figures 1 to 16, illustrates a specific cleaning system. In this embodiment, the cleaning system is a floor scrubber system, comprising a cleaning device 10 and a base station 20. The cleaning device 10 is used to clean the floor, including but not limited to vacuuming and mopping. The base station 20 is used for maintaining the floor scrubber, including but not limited to self-cleaning, charging, drying, sterilizing, draining, and replenishing cleaning solution for the cleaning device 10.

[0129] Specifically, the cleaning device 10 includes a handle 110, a body 120, and a floor brush assembly 130 rotatably connected to the body. The body houses a power unit 160, a main unit clean water tank 140, and a main unit waste water tank 150, all located at the rear of the device. The power unit 160 can be a detachable structure, including a battery pack, a suction device 170, and an airflow reversing structure 180. The battery pack, suction device 170, airflow reversing structure 180, main unit clean water tank 140, and main unit waste water tank 150 are arranged sequentially from top to bottom.

[0130] The airflow reversing structure 180 includes a first reversing housing 181, a second reversing housing 183, a first movable member 182, a second movable member 184, a first sealing structure 186, a second sealing structure 187, and a reversing drive member 185. The description of the airflow reversing structure 180 can be referred to the above embodiments, and will not be elaborated here.

[0131] The cleaning equipment 10 is equipped with a sewage inlet pipe, and a sewage suction cover 151 is pivotally connected to the sewage outlet of the sewage inlet pipe. The sewage suction cover 151 can be made of soft rubber.

[0132] The bottom of the main unit's sewage tank 150 is provided with a sewage outlet 153 and a sewage cover 156 pivotally connected to the sewage outlet 153.

[0133] The floor brush assembly 130 includes a floor brush housing, a roller brush, a roller brush motor, a water pump, rollers, a dust indicator light, etc.

[0134] The base station 20 includes a tray 210 and a base station body 220. The tray 210 is located below the base station body 220 and has a cleaning groove for placing the floor brush assembly 130, a groove for placing the rollers, an accessory storage area, and other structures. The base station body 220 extends upward and includes a base station housing. The base station housing may house a base station wastewater tank 225, a wastewater collection pipe 224, a liquid injection assembly, an automatic drainage structure, etc. The base station 20 may also house a cleaning liquid mixing assembly, a heating assembly, a UV lamp, etc., which are not listed here.

[0135] The docking point between the base station body 220 and the cleaning equipment 10 is provided with a sewage collection port 221, a liquid injection port 222, and a base station charging terminal 223. When the cleaning equipment 10 is docked with the base station 20, the sewage discharge port 153 and the sewage collection port 221 are docked, the liquid replenishment port of the cleaning equipment 10 and the liquid injection port 222 are docked, and the main unit charging terminal and the base station charging terminal 223 are docked.

[0136] The cleaning system of this embodiment can perform a suction mode and a discharge mode. When the suction mode is performed, the water spray component on the floor brush assembly 130 sprays water onto the roller brush and / or the floor, causing the roller brush to clean the floor. The controller controls the airflow reversing structure 180 to be in a first conducting state and controls the discharge drive to drive the discharge cover 156 to close or open. The suction device 170 is activated, and airflow flows from the main unit wastewater tank 150 to the suction device 170 and out from the air outlet of the suction device 170. The main unit wastewater tank 150 is under negative pressure, and the suction cover 151 opens under the action of negative pressure, thereby sucking the wastewater generated from cleaning the floor into the main unit wastewater tank 150.

[0137] When the cleaning equipment 10 is connected to the base station 20, and the sewage discharge mode is executed, the suction cover 151 is in the reset state, covering the sewage outlet of the sewage inlet pipe. The controller controls the sewage discharge drive to open the sewage discharge cover 156 and controls the airflow reversing structure 180 to be in the second conduction state. The suction device 170 works, and the airflow enters the airflow reversing structure 180 and the suction device 170 from the outside atmosphere, and flows out from the bottom of the airflow reversing structure 180 into the main unit sewage tank 150. The main unit sewage tank 150 is under positive pressure, which causes the sewage in the main unit sewage tank 150 to enter the base station 20 through the sewage outlet 153. After passing through the sewage collection pipe 224 and the base station sewage tank 225 of the base station 20, it is discharged into the municipal pipeline.
